Yeah Stafford has always had a "throw it up and expect my WRs to make a play a couple times a game" mentality. Once in a while it creates an issue but I think ultimately it makes him the QB he is and defenses have to always respect that possibility.
But he also mentioned having a "surgical thing" done this past month and was apparently playing through something this season all though it was never disclosed other than a toe issue and some back/throwing arm soreness (which to be fair he's 34, that's just part of life for him now). Hard to say what but I think it certainly affected him somewhat. I couldn't find the exact article but this one seems to mention them.
According to Charean Williams of Pro Football Talk and Cameron DaSilva of Rams Wire, Stafford revealed on Tuesday he had a "surgical thing" this offseason. The 34-year-old didn't offer specifics about the procedure other than saying that it "is going to make me feel better in the long run."
Per DaSilva, Stafford was on the team's official injury report ahead of January's playoff win over the Arizona Cardinals with a toe problem. He also dealt with "chronic back pain and pain in his throwing arm back in November." According to the NFL's website, Stafford had an anti-inflammatory shot in March that left him requiring a brace for his arm.
As noted by ESPN stats, Stafford finished the 2021 regular season third in the league with 4,886 passing yards, second with 41 touchdowns through the air, sixth among eligible quarterbacks with a 102.9 passer rating, and fourth with a 63.8 total QBR. One wonders if he'll enjoy even more success during his second campaign with the Rams following his recent procedure.
