I've been meaning to mention this about Buchner. This is gonna sound strange but as someone who has studied this area extensively and is affected by these same issues, I can see that Buchner likely has airway/disordered breathing issues that (can't get into the details here) affect his entire body and mental makeup, the three most important of which are executive decision making, proper nose breathing and optimized skeletal structure: 1) He looks to be a mouth-breather - mouth is always open and probably is a shallow breather; 2) You can see his nervous, stream of consciousness thought process when he speaks to reporters compared to say Hartman; 3) he is clumsy (remember his stairs injury) and is easily injured; and 4) as a number of IE posters mentioned, he's nervous and "not composed" or "doesn't have mental toughness," etc. when he is in the pocket so he tends to tuck and run and not hang in for his progressions. This is a real thing and many people are affected by this but the individual just thinks "this is how I am," but it's not an optimized state of functioning. Sure, TB has the measurables/arm skills and is smart in other ways and is truly a "warrior," and with A LOT of work/coaching/development, he may develop and get better (and he'll have his moments like the '22 Bowl game), but he doesn't have the natural QB attributes, presence, and focus, and it will always be a challenge for him to be consistent and truly excel at QB. I could be wrong, but you just don't see the things I outlined here in star QBs. And I would say that the other ND QBs (and JJ McCarthy) don't have these issues and instead have more natural executive presence and decision-making abilities. Bryce Young is a perfect example of maybe not the most physically blessed QB, but he has the presence and focus to become a star NFL QB like Russell Wilson, another undersized but hyper-focused QB in this mold. Just my two cents anyway.
