It is possible, though the term "elite" is undefined and nebulous at best, but my point was alluding to the statement that someone has to much "heart" to fail.This is true except Tua is not without talent. He has displayed elite level processing and accuracy before the injury, why is that not possible to return after an intensely dedicated offseason???
Guys with heart the size of Texas fail at the highest level all the time, do to limitations beyond their control.
I even went out of my way to say it was a general comment, and not reflective of my opinion on Tua.
