I feel like they are only 2 no doubt elite QB’s currently (Burrow and Mahomes) and maybe Allen (depending on the day). Then there are lots of young QBs with promise, but nothing that would show consistent excellence yet. The largest group is the pretty good QB-they differ very little among themselves and go as the rest of the squad goes-they look great on a great team and terrible on a terrible team and mediocre on a mediocre team (when you look over the entire season performance). Only a couple truly dreadful QB’s and they are typically backups or out of the league very quickly.
Signature performances are typically wins that occur in the postseason-though there can be a foreshadowing regular season win that is backed up in the playoffs (of course the QB has to perform great in those wins).
I’m starting to feel that if a team does not have an elite QB, the team should give the QB a maximum of six years (utilizing franchise tags), for the QB to take the team to at least a CCG. Otherwise, the team should move on to another QB no matter what the stats say (unless the team ranks bottom 5 in points given up every single season). Line of scrimmage dominance can make QB’s from the largest group above appear competent and oooh ahhhh. For the largest group of QBs, I feel like the offensive and defensive lines are the most important position(s) for this largest group of QBs. Then receivers/tight ends. Than the QB. Then linebackers and secondary. Then running back.
I believe that most professional QB’s that have a terrible season can usually point to a poor offensive line and/or weapons. Lots of JAGs and a few diamonds.
