He is clearly still NFL caliber, he's just not all that good anymore.
There is a serious lack of good NFL QBs in 2023.
Mahomes, Allen, Prescott, Rodgers, Jackson, Hurts, Herbert, Stroud, Burrow. Perhaps guys like Lawrence, Tua, Stafford, and Goff, too. Baker has been ok.
But I couldn't even get to 16. More than half the league has bad QBs. It doesn't help that defenders get better and better each year. EDGE rushers and OLBs get scary fast AND strong while offensive lineman are diamonds in the rough to find good ones.
Add that up and you have the current NFL landscape.
I have no doubt Wilson could go to a different team and have a 30:15 TD:INT ratio next season but I still wouldn't trust him to win me a meaningful game.
