What happens a lot of times is these kids who all there lives a superior athletes so use to being enabled in so many ways and there athleticism makes up for any weakness they may have.
Like if a play is called and they misunderstand there route ( example) they can correct instantly on the fly and make huge plays . Never understanding what was the correct read and so on.
Plus a D-I playbook is super complicated with hundreds of options depending on D or O reads .
It really is complicated, I myself would need hours upon hours of help to understand.
When these kids find out there 5 star means zippo and there not 1st string anymore and on scout teams for couple years till they’re thinking stops and they can run routes like X does on instinct and be spot on

timed with QB and others.
When they are weak mentally in this the drop happens wrong routes causing interceptions and so on to occur.
Now there athleticism gets depressed and the 5 star player he used to be is gone causing blaming others for what there dealing with and there play slows down.
I’m not sure I’m coming close to explaining how weak mindedness sets it .
It can be so bad that every action they do has zero confidence to the point they panic and want to leave in desperation.
Brother it’s hard to put into words what goes thru an athletes mind in dealing with adversity in there game for the first time in there lives especially at D-I level.
I remember how Jimmy Johnson found Jimmy Jones a # 2 NFL DALLAS draft choice.
He went to see a 5 star player high school at practice and this huge kid was standing there crying watching his team practice.
JJ ask why aren’t you practicing, Jones said I can’t I have to stop playing yo go to work for my mom.
JJ ask young man I want you to play DT for me at Miami rest is history.
See this kids never ever had a break nothing given to him struggled in every way never was enabled and when he got to Miami he exploded to NFL level.
Again I hope I explained myself and my overflowing thoughts didn’t mess my explanation up to bad LOLOLOL
