Will Matthew Stafford fold under pressure? If you were disappointed with Jimmy Garoppolo’s performance in game one against the Viking’s elite defense Fred Warner Jersey , well, Lions fans were disgusted with Matt Stafford’s effort against the somewhat-less-impressive New York Jets. At Pride of Detroit, Jeremy Reisman wrote that:Stafford had four interceptions, and it was far from the first time that has happened. Since he entered the league in 2009, he leads all quarterbacks with five games of four interception each. And he had Calvin Johnson to throw to for most of that time.This brings up a long-running debate: does Stafford fold under pressure? It matters because he can expect to face a lot of pressure Sunday, against a 49ers pass rush finding its stride and facing a Lions offense with no discernible running game and a shaky offensive line. Lions starting right guard T.J. Lang is confirmed out, injured, so the newly effective front line of DeForest Buckner, Arik Armstead and Solomon Thomas will be facing the likes of rookie center Frank Ragnow and marginal veteran guard Kenny Wiggins, who wasn’t even good in the preseason.Stafford has faced accusations of folding under pressure since 2012, when Chicago Bears safety Major Wright said:In 2015, he was benched in the second half against Arizona after throwing his third interception of the night, and Neil Greenberg of the Washington Post wrote that:Later that year, the Lions brought in offensive coordinator Jim Bob Cooter, who put in a quick- (and short-) passing offense that limited Stafford turnovers as well as his big plays. Not a mark of great confidence.Of course there are some hometown voices who are more positive. Last year, Ty Schalter of LionsWire emphasized the fact that that in 2017, “Pro Football Focus charted him No. 3 in yards thrown under pressure.” This is true, but notice that Schalter’s not quoting passer rating under pressure, just total yards.What this statistic is really telling you is that Stafford was under pressure all the time last year, because their offensive line was terrible.A more nuanced take comes directly from PFF, in their Lions preview this year.While they were optimistic about Detroit’s off-season investment in the OL — which hasn’t paid off so far due to injury and the talented Ragnow’s lack of experience — they broke down Stafford’s numbers this way.Their basic point is that Solomon Thomas Jersey , at this point in his career, Stafford isn’t bad under pressure. What he is, is great when he’s NOT under pressure, and mediocre when he’s sweating. I’ve bolded the key parts of this paragraph:There aren’t many quarterbacks who don’t decline when under pressure. Jimmy G might be one of them, but Matt Stafford is definitely not. As long as Robert Saleh and new pass rush coach Chris Kiffin can continue their success in game one, the Niners defense should give Stafford a lot of problems on Sunday.49ers depth chart updated to reflect Jimmy Garoppolo injury, new linebacker lineup The San Francisco 49ers travel south in Week 4 to face the Los Angeles Chargers, and with that game comes a shake-up in the depth chart. The team’s PR department released the unofficial depth chart on Tuesday, and a slightly major move on Wednesday has resulted in a change.The 49ers have placed Jimmy Garoppolo on injured reserve and promoted Nick Mullens from the practice squad. The initial unofficial depth chart listed C.J. Beathard as the starter and Garoppolo in brackets for his injury. I have removed him and added Mullens in. The team is sticking with two quarterbacks for the time being.The PR department also formally moved Malcolm Smith into the SAM spot, Fred Warner into the MIKE spot, and Reuben Foster into the WILL spot. This is a formalization of what we’ve already seen. As long as Smith remains healthy, it looks like he’ll be the SAM the rest of the way, with Mark Nzeocha handling backup work.The running back situation is currently listed as Matt Breida or Alfred Morris as the No. 1 running back. They are splitting the workload pretty evenly, but Breida is starting to emerge as the more successful back, leading the league in rushing yards and yards per carry. One has to wonder if at some point the 49ers will be willing to remove the “OR,” or if they think his success is built in part on having someone like Morris to offset his workload.49ers offensive depth chart, Week 4 vs. ChargersPositionFirstSecondThirdPositionFirstSecondThird49ers defensive depth chart, Week 4 vs. ChargersPositionFirstSecondThirdPositionFirstSecondThird49ers special teams depth chart, Week 4 vs. ChargersPositionFirstSecondThirdPositionFirstSecondThird
