who their quarterback will be on Thursday when they host the Oakland Raiders. Well Tevin Coleman Jersey , they are not publicly acknowledging who will it be, other than to say it will be a game-time decision with C.J. Beathard.Regardless of who is playing quarterback, one big issue will be the Raiders pass rush — or should I say, lack thereof. The 49ers offensive line has struggled in pass protection, but the Raiders pass rush has been the worst in the NFL. Here are some notable stats regarding the Raiders struggles getting to the quarterback.7 sacks: ranks 32nd56 QB pressures: ranks 32nd20 QB hits: ranks 32nd3.1% adjusted sack rate: ranks 32ndBy comparison, the 49ers rank 26th in adjusted sack rate, and 25th in Pro Football Focus’ pass blocking efficiency stat.Something has to give in this matchup, and it could be a difference-maker for the 49ers. When there has been no pressure this season, Beathard has completed 66.1 percent of his passes, and PFF grades him out at 80.7. When he has been under pressure Nick Mullens Jersey , he completes 44.4 percent of his passes, grades out at 43.3 on PFF’s grading system, and ranks 33rd in passer rating.Nick Mullens has yet to appear in the regular season, but did get 47 dropbacks during the preseason. He completed 78.6 percent of his passes (22 of 28) when not under pressure, and graded out at 90.1. When pressured, he completed 60 percent of his passes (9 of 15), and graded out at 42.9.If the 49ers are going to handle their business and win this game, it will be critical Beathard or Mullens has time to operate in the pocket. Of course, it will also be incumbent on the quarterback to make quick decisions to keep things moving. The 49ers offensive line has been hit or miss in pass protection, but this game provides the unit an opportunity to head into the second half of the season with at least a modicum of moment. Kyle Shanahan and company looking at another big WR?"On Thursday morning Alfred Morris Jersey , the Stanford Cardinal held their Pro Day. John Lynch, former alumni, was on hand. As was head coach Kyle Shanahan. There were plenty more names that you’ll recognize on the San Francisco 49ers staff. Wide receivers coach Wes Welker was present. Offensive assistant Katie Sowers was with Welker, too. Lastly, special teams coordinator Richard Hightower was there as well.Hightower is likely looking at Stanford punter Jake Bailey. Bailey averaged 44.1 yards per attempt in 2018. WR J.J. Arcega-Whiteside is probably the player that the team was keeping an eye on. Arcega-Whiteside is 6’2, 225 pounds. He’s a very good athlete that was miscast at Stanford. He should have a much better career in the NFL. He also ran a 4.49 at the Pro Day today.As a receiver, Arcega-Whiteside moves a lot better than you would expect for a player his size. He’s a good route runner that can also go up and get it. Seems to be a perfect blend at the position for what Shanahan covets. Watch these four routes against Oregon:A bigger guy that can win the contested catch situations, but can also run away from you. Everyone was waiting to see what his timed speed was. There it is.We’ll keep you updated if any of his shuttle drills are leaked.
