I know it's just practice, but notice his footwork vs the other QBs. On deep throws, he seems to jump and swing his throwing foot leg around: Jumping Julian Sayin. You don't notice the other QBs doing that. You don't notice it as much on his first throw at about :30, but at around 1:03 he seems to practically jump and swing his leg around to generate power on the long ball, like he's throwing a javelin or something. I question how effective that will be against a good defense where you won't have that much room to throw. He's #10, by the way.
