I don't think I saw it last night, but I've seen other games where McD is actively talking on the headset and covering his mouth with a playsheet while the team is on OFFENSE. It suggests to me that he is more active in the play calling vs. just delegating to Dorsey. I could be wrong, but I think his nature is to be very controlling. That said, they should still move on from Dorsey....the sooner the better.
