The San Francisco 49ers officially named Nick Mullens their starting quarterback Tuesday for the team’s Week 10 matchup against the New York Giants on Monday Night Football at Levi’s Stadium. The quarterback informed the media during Tuesday’s post-practice availability.Monday will be Mullens’ second consecutive primetime start after making his debut against the Oakland Raiders on Thursday Night Football in Week 9. The 49ers’ backup-turned-starter completed 16 of 22 passes (72%) for 262 yards Rookie Nick Mullens Jersey , three touchdowns, zero turnovers and a nearly-perfect 151.9 quarterback rating.Mullens was inserted into the starting lineup after C.J. Beathard struggled to grip the football throughout the short week leading up to the Raiders. The former starter injured his throwing hand in the second quarter of the 49ers’ Week 8 loss to the Arizona Cardinals. It was Beathard’s fifth straight loss in five starts this season, now 1-9 in his career as the 49ers’ starter.Mullen’s stellar showing is on the short list for greatest debut performances ever by an NFL quarterback. He played so well that Twitter verified his account during the game.“You never know until you see someone,” Kyle Shanahan said post-game Thursday when asked if he was surprised by Mullens’ debut. “He didn’t surprise us in terms of Nick Mullens Jersey , the game’s not too big for Nick. He’s very poised. He is always locked in. The guys, they respect him.”Mullens gets another chance to impress Monday under the lights of primetime against a vulnerable Giants defense. It’s the silver linings at this point. DeForest Buckner was at one point going from his nickname of “DeFo” to “DPOY” (That’s defensive player of the year). Unfortunately, with injuries, defensive miscues and other things Nick Mullens 49ers Jersey , that most likely will not happen in 2018. But he’s still improving from 2017. In 2016, Buckner had six sacks for the entire season. Last season, he had three sacks. Buckner was credited for a half sack on Monday against the New York Giants, which bring shim to six sacks on the season. He has yet to surpass his 2.5 sack performance in Week 1 against the Minnesota Vikings Cheap Jimmy Garoppolo Jersey , but he’s well on track for a career high performance. One problem: This is the 49ers pass rush we’re talking about here, and Buckner has gone a few spells without a single sack to his name. The 49ers face enough inconsistent offensive lines the rest of the way that I don’t see how Buckner cannot inflate that sack total. Buckner refused to reveal his goal in 2018 for sacks, so we’ll have to wait until the offseason to see if he’s playing to expectations. DPOY or no, Buckner has become a centerpiece of the 49ers’ defense and he’s going to be getting a big payday sooner rather than later.
