So where did it disappear? I can;t be talent, but if a qb doesn't have potential it's mental. Because he would never have been rated by nfl talent scouts and ppl who know more than your couch sitting fans. Coaches etc and he was touted at just a level below lawrence and luck. It's not just mental, but you have to have top tier physical talent to be rated that high. It's more of a matter of handling pressure and reading defenses and learning which is still too early to see if that talent comes out or it doesn't. It's not the lack of talent, but learning the game and reaching that potential. The top 5 qbs who are busts or don't become franchise qbs are one's who can't do it mentally to translate with their physical talent, which with that physical talent is high potential. Tua has strong potential or else not regarded so highly, its just still early to see if he brings it out while still learning the game.
