LSU Playbook is it too simple and too short.?

Wonder what the consensus of Ranters opinion on Tiger play calling. I noticed during the game Met checking the plays written on his wrist. I thought by the end of season he would have memorized the plays by now. Are our pass routes to simple or just not executed properly. Do we have too few plays to call so that our options are limited. Kansas State's Bill Snyder said he had tons of plays and variations in his playbook.
Of course he is the coach of the year. I know talent determines what plays you can call but i always hear about how talented our team is. So are is our playbook too simple, plays not called correctly for the opposing defense, or just not executed properly?
