All you Tua doubters need to listen and take some notes.
Trent Dilfer, former Super Bowl winning QB and head of Elite 11 (the biggest QB development program going) says that of the kids coming through he's coached (Wentz, Goff, Darnold, and Rosen lol included) that Tua is the most special he's ever seen. (this part starts at 2:20)
Says his arm talent, quickness of release, foot energy, and sheer lower half strength can match up with any of them...but yet none of those are his best traits. He instead says Tua is the best LEARNER he's ever been around. That he would pick up critiques about his game and turn them into strengths in an absurdly quick fashion.
It's a bit long but really a great listen. Dude just seems to have franchise elevator written all over him. 2020 draft and season can't come fast enough.
