Still comes down to reps and situations. There aren’t enough reps in a game week to split 50/50. Hence, limited play selection for the #2 for the week especially in situational opportunities. I agree that AR should have access to most if not all the playbook b/c of the similar chakra stick of both players. I just dont think DM would send in the #2 to run something not repped in practice a substantial amount of time for the given situation. Keep in mind it is possible to go with a scripted approach for a drive where the whole drive is scripted like the opening series for the game. The only time recently i remember DM Mullen opening the playbook was AU 2 years ago when KT left in the 2nd Q. EJ had a lot of varied plays on the one drive.
