I think McCoy was awful, and probably way too complicated, but I'm also concerned about Kliff being too simple. This isn't the flash-card college offense he's used to calling.
I like that he addressed dealing with adversity/failure. I also thought a good point was brought up with him having to learn to deal with constant failure in baseball. In baseball you will make errors, be made to look foolish at the plate quite a bit while going through hitting slumps and of course losing plenty of games.
As long as you are changing up your signals and terminology from game to game than I don't think it much matters how simple it is. Ultimately it all comes down to the coach and the QB countering what the oposing defense is trying to do and a lot of those adjustements will be made at the line of scrimmage after the play has been called and the team has lined up.
