I recall one of the announcers stating that on run plays he held his hands lower to the ground before the snap or something like that.
I'm sure it's a problem that has been addressed and corrected.
I have two concerns with Edwards, durability and ability to play in the cold. When he injured himself against the Jets last year I don't recall there ever being an "official" diagnosis as to what happened, all that was reported was that he had trouble gripping the ball. He also should have been coached out of wearing that god-awful glove, it seemed to strongly affect his normally solid accuracy.
Sit and wait, that's really all that any of us can do right now. Hopefully the rookie cobwebs have been worked out.
