Yeah, and the thing is I completely agree with you about letting QBs develop and sit and learn and I've been a huge advocate for doing that deliberately and being patient while ignoring the pressure to start a young rookie. I think the best way forward at the QB position is to get a somewhat established fringe or mid-tier starter vet in FA or trade and stick with him while drafting a QB relatively high and having him sit a year or even two. The Packers, and Chiefs method.
But all that said, there are very very few examples of QBs who struggled in both their first 2 seasons who became legit franchise QBs. Guys like Darnold and Geno Smith are breaking that mold a tiny little bit, although jury is very much out on whether those guys are actual "franchise QBs" or guys who would be capable of winning a SB even in a great situation. But historically and even recent history suggests that if a QB doesn't look the part within his first 2 full seasons of starting then it isn't going to happen and you should just move on. And Bryce now very clearly has not looked the part into his 3rd season, and with a ton of investment on offense and a "QB guru" coaching staff. The excuses have completely dried up with him. It sucks but it's the reality Bryce fans need to accept at this point.
I don't know why teams who have been searching for their QB forever keep sticking with mediocrity for way too long. If they haven't shown franchise QB level by year 3, move on and rinse and repeat and draft another guy. Keep doing it until someone sticks. The other reality is that coaching and front office matter more in the big picture than who your QB is at that moment. Just look at the success Andy Reid had with Alex friggin Smith as his QB in KC before Mahomes showed up and the Eagles the last decade or so. The sole focus from Tepper should be on building out a steady and consistent top tier front office (who then hires coaching staff) who has a clear vision and plan for the team, including the future at the QB position. Not being hands on meeting with guys like Bryce and CJ before the draft and having dinners with their families, etc. I digress
