This guy is impressive with the one handed catches. However, all the videos i have seen thus far where he makes this kind of acrobatic catch, the ball seems to be under thrown. Surely that was the case in the game video where he one handed the ball on that deep route.
While there are under throws in this league, the guys tossing the rock are pretty darn accurate and get the ball deep enough for the corner to be shielded by the receiver.
Not saying he will be bad. Or even that he won't be a real player. Just appears to me the under throw offers him a chance in an amateur sport that will not come with any regularity in the pros.
