I think coaching is exactly it. Not that it's all on coaching with EJ, but he seems so worried about turning the ball over that he checks down or is tentative with his throws. It is a different kind of tentative than Edwards suffered from. I don't thimk EJ is scared, he is so worried about the interception his mechanics become bad. As I've said before, his best drives have been two minute drills or over time.
That being said Geno is a turn over machine.
