Anybody that knows anything about throwing the rock, look at how he does his wrist, and his release, on that throw.
It shows a little bit of sophistication in the throw and release point, and the way he slightly rotates the motion through his wrist and hand, in other words, he was taking something off that throw, again, for anybody that knows how to throw the rock you’ll see what I’m saying.
Just one caveat: I never played quarterback nor do I pretend to be a QB expert, but I’ve seen plenty of people, follow it, and anybody that has the XY chromosomes can’t help but throw the ball when you get it in your hands
