I was doing a bit more digging on Mythical Max, and liked this YouTube clip of one of his games last year. He's doing a lot of stuff that AK wasn't:
- Going through the progression of his wide receivers and throwing the pass to the guy that's open (versus throwing to receiver 1 even if he's in double coverage).
- Putting touch on the pass when it's needed, vs 100 mph fastballs on everything.
- Being accurate with his passes - hitting receivers in stride.
The other item is that IMO he has a really quick release. A lot of QBs tend to have a bit of a wind-up in their passes, when he decides to throw it, it gets out of his hand really quick.
