It's hard to say they aren't that similar

Prescott is stronger looking and doesn't take stupid chances like Griffin did.

He's also smarter about when he runs, he isn't looking to take off after 2 seconds like Griffin was. And he will dash out of the pocket and get rid of the ball where Griffin used to just keep running trying to do something. And usually paid a price for that.

I'm not the least bit surprised that Griffin isn't on a roster right now by the way.
