There’s only two games left for the San Francisco 49ers and their 2018 season. Kyle Shanahan’s team is riding their first win streak of the season after topping the Denver Broncos in Week 15 and the Seattle Seahawks on Sunday in overtime. Now the 49ers face their stiffest test of the group Nick Mullens Color Rush Jersey , hosting the playoff-bound Chicago Bears at Levi’s Stadium for the last of three consecutive home games. We’re back with this week’s mailbag before the 49ers’ Week 16 matchup. You’re welcome to drop questions in here for next week’s mailbag or tweet me @Rob_Lowder.“As it pertains to Mullens’ contract can you please explain what it means being an exclusive rights free agent (ERFA)?How would this affect Mullens’ timeline of being a Niner, being tendered and possibly being traded?” Jon JustusJason Fitzgerald of Over The Cap had this to say on Exclusive Rights Free Agents:Mullens belongs to the 49ers. He's signed through the 2019 season at a minimum cap number of $570K, and will be an ERFA after 2019. If he is signed for 2020, he would be a restricted free agent in spring 2021. As an RFA, the 49ers could place a first round tender, second round tender, or original round tender. If he signed a tender then, he would become an unrestricted free agent in the spring of 2022.This would making him very appealing for any team interested in making an offer to the 49ers. Any team that acquired Mullens would have him on the cheap for at least a season to evaluate him in their own system. It’s doubtful the 49ers move on from Mullens, though, especially while Garoppolo recovers from his torn ACL. Pending an offer too good to turn down, Mullens should be on the roster in 2019 competing for the backup role along with C.J. Beathard.“How should the 49ers address the lack of not having a pure pass rusher in the offseason? Who should they target in free agency/draft?” Valentin GarciaThe 49ers’ lack of an edge rusher is likely the team’s No. 1 priority heading into the offseason. Luckily, general manager John Lynch will have a handful of options available to him in both the draft and free agency. Here’s a list of the top pass rushers scheduled to hit the free agency. Many of them will be retained by their former team with either a new deal or the franchise tag:Ezekiel Ansah, Detroit LionsFrank Clark, Seattle SeahawksJadeveon Clowney, Houston TexansTrey Flowers, New England PatriotsDee Ford, Kansas City ChiefsDeMarcus Lawrence http://www.49erscheapstore.com/nick-bosa-jersey-cheap , Dallas CowboysFor options in the NFL Draft, we’ll move on to our next question...“With Nick Bosa likely being out of reach....do we take the next pass rusher available wherever we land or Greedy Williams if available?” BenjaminThe 49ers’ pass rush options in the draft depend on where they pick and who’s on the board. LSU cornerback Greedy Williams is certainly a good option at a position of need that is widely ranked in the Top 5-10 on most draft boards. If Ohio State’s Nick Bosa or Kentucky’s Josh Allen are available, it’s a pretty easy choice. After that, if a pass rusher is still the target, the 49ers would be wise to seek a trade partner to avoid reaching. Here are the edge rushers that fall within Matt Miller’s Top 50:No. 1 overall: Nick Bosa, Ohio StateNo. 3: Josh Allen, KentuckyNo. 14: Brian Burns, Florida StateNo. 17: Jachai Polite, FloridaNo. 18: Clelin Ferrell, ClemsonNo. 21: Montez Sweat, Mississippi State“What you think about Earl Thomas in 49ers?” Yuri SilvaSeahawks safety Earl Thomas should be near the top of the 49ers’ priority list for pending free agents. The free safety position is crucial in coordinator Robert Saleh’s scheme, which is nearly identical to Seattle’s. The 49ers should employ Richard Sherman as ambassador to Thomas in the hopes that the veteran cornerback can lure his former teammate to San Francisco. Thomas, in the last year of his contract, began the offseason with an unsuccessful holdout in hopes for a new deal. Four games into the season, Thomas broke his leg and his season was over. It’s safe to say there’s no love lost between he and the Seahawks. Joining the 49ers may be Thomas’ best avenue if he wishes to say thank you twice a year for the next few seasons.“Who are the targets the 49ers should go after in free agency? (I like Anthony Barr, Earl Thomas, Brandon Graham)” Michael DarmofalskiMichael presents some solid options that would all prove immediate upgrades on the 49ers’ roster that still has a handful of needs at crucial positions. The 49ers are projected to have nearly $70 million in salary cap space before any additional roster cuts. First Cheap Nick Bosa Jersey , re-sign kicker Robbie Gould. Then the 49ers should take a look at this list of free agents that would all have a significant role on the team:S Earl Thomas, Seattle SeahawksLB Dee Ford, Kansas City ChiefsWR Tyrell Williams, Los Angeles ChargersCB Rashaan Melvin, Oakland RaidersDE Brandon Graham, Philadelphia EaglesLB Anthony Barr, Minnesota Vikings“FS/SS/NCB battle in 2019? Who you got?” J BookFree safety, strong safety and nickel cornerback are positions on the 49ers’ defense that will likely feature competition for the starting spot in the offseason. It’s difficult to know how those will play out without any free agent additions or draft selections accounted for, but for now I’ll choose players on the roster most likely to start in 2019:Free safety: Jaquiski Tartt over Adrian ColbertStrong safety: Marcell Harris over Jaquiski TarttNickel cornerback: D.J. Reed Jr. over K’Waun Williams“What are your thoughts on going CB in the draft (say Greedy Williams) and splashing on a pass rusher like Dee Ford or Frank Clark in FA?” Simon ASelecting a cornerback in the first round and targeting a premier pass rusher in free agency would do wonders for the roster. LSU cornerback Greedy Williams is considered the draft’s top option while Kansas City’s Dee Ford is among free agency’s best pass rushers. It’s still unclear if the Chiefs will allow Ford to hit the open market. Seahawks’ Frank Clark has put together an outstanding season, and while his reputation off the field isn’t sterling, he’d still be a significant upgrade for the 49ers.“Since we will more than likely address the pass rush in the draft, what WR do you think the 49ers throw their money towards in free agency? Watching some of the plays can’t help but wonder if we had a bigger more physical WR?” Kristi CruzThere’s a good chance the 49ers address both the pass rush and receiving corps in both the draft and free agency. 2019’s crop of free agent receivers isn’t all that inspiring but there’s still some intriguing options to explore. Los Angeles Chargers wideout Tyrell Williams (26) is worth exploring. The 6-foot-4, 215-pound receiver has totaled 38 receptions for 614 yards and five touchdowns so far in 2018, and that’s within a group consisting of Keenan Allen and Mike Williams. Philadelphia Eagles’ Jordan Matthews, Cleveland Brown’s Rashard Higgins and Tampa Bay Buccaneers’ Adam Humpries are some other under-the-radar names to keep an eye on.“Out of the second year players who have struggled, which one has the best chance to rebound?” ZmanIs there any other choice than Solomon Thomas? The 49ers’ second-year defensive lineman has struggled to establish himself as the impact player you would expect from the third-overall pick. Thomas hasn’t struggled as much as he has failed to stand out, playing under the shadow of the two first-round defensive lineman that came before him Nick Bosa 49ers Jersey , DeForest Buckner and Arik Armstead. Thomas has totaled 23 tackles, three tackles for loss, six quarterback hits and a sack this season. He’s steadily improving though, which brings us to our last question of the day...“By the eye test, Solly Thomas had a solid game and arguably his best. Do the advanced stats back that up?” Holmgrown NFLThomas earned a Pro Football Focus grade of 73.8 against the Seahawks on Sunday, the second-best grade on the 49ers’ defense. His run grade of 71.9 ranked fifth, and his pass rush grade of 64.5 ranked fourth. While he did pressure Wilson twice, a lot of Thomas’ success on Sunday didn’t show up on stat sheet, which is why I’ll leave you with the great Brian Baldinger to show you Thomas’ impact against the Seahawks like only he can: SANTA CLARA, Calif. (AP) — Defensive end Nick Bosa made it through his first NFL practice without injuring himself Saturday morning at 49ers training camp.Bosa is coming off a torn bilateral core muscle, an injury which ended his final season at Ohio State. After the 49ers drafted Bosa with the second pick in April’s draft, he pulled his hamstring during the first practice of the offseason while participating in a one-on-one pass-rush drill. He missed the rest of OTAs and minicamp.Now, the 49ers have cleared Bosa to do everything in training camp.“You always want them to go to OTAs as a rookie, because you throw a lot at them,” coach Kyle Shanahan said. “But, you don’t judge guys in OTAs, especially rookies. They just learn the playbook http://www.49ersfanshop.com/Nick-Bosa-Jersey , do a few things, get away, come back, and it’s time to go. Bosa got hurt the first day, so he wasn’t able to practice, but at least he was around here. He got to do everything except rush the passer, and rushing the passer is something he’s done his whole life. Now he’s just got to get back in to practice and get used to going against NFL O-linemen. I don’t really consider him behind.”Bosa mostly played left end for the second-string base defense Saturday. But on third downs he played with the starters. And during his first play with the first-string defense, Bosa beat six-time Pro Bowl left tackle Joe Staley around the edge and almost stripped the ball from quarterback Jimmy Garoppolo’s hands.“(Bosa) got Joe a couple times today,” defensive coordinator Robert Saleh said. “But, Joe is a seasoned vet. (Bosa) is going to find out very quickly that offensive linemen adjust in this league. He’ll get a chance tomorrow to see where he falls after Joe makes his adjustments. Bosa has a chance to be great, but he’s got to understand he’s got to develop his game, otherwise they’ll figure him out real quick.”Bosa is the younger brother of Los Angeles Chargers defensive end Joey Bosa, the 2016 Defensive Rookie of the Year, who has 28 1-2 sacks in 33 career games. In college, Nick Bosa had 17 1-2 sacks in 29 games.The 49ers did not make Bosa available to the media Saturday.“He has a great football pedigree,” right tackle Mike McGlinchey said. “He’s very polished as a pass rusher for a kid who is just 21 years old. He looks like this big, powerful guy Nick Bosa Color Rush Jersey , but he’s smart enough to be able to use his hands, get down and bend around the corner. He put that on display today, which was pretty cool to see.”Like his older brother, Bosa uses fluid hips and violent hands to beat offensive linemen to the quarterback. “Bosa wins in close quarters,” Saleh explained. “He wants you as close to him as possible, and then he just has an ability to flip his hips and get skinny in close quarters where most people need space so they can knock arms down and create angles for themselves.“With Mike Tyson, the closer you got to him, the more trouble you were in because he loved to be in there tight. Same thing with (Bosa). He just gets in there tight, and then he can work his body and hands. His hand-eye coordination is pretty good.”Bosa showed how good his hand-eye coordination is when he beat Staley around the edge. But there is a long way to go.“For me, he’s a rookie with a helmet and no pads right now,” Saleh said. “I just want to see him get better, be deliberate in his practice and see how good he can get.”NOTES: The 49ers signed DL Jordan Thompson to a one-year deal.
