OP is spot on. It's unfortunate, but it is reality.
Normally, former coordinators have learned enough about game management to eliminate that as an issue. I really can't remember another coordinator turned head coach that seemed as unprepared as Rivera on game day. He flat out doesn't understand clock management, 2 minute drills, when to accept/decline penalties, etc. How is that even possible? How can you spend that much time around the game and not understand some of the most fundamental stuff?
I rewatched part of the Seattle game last night. There was a sequence when either we were in the red zone or Seattle was. I don't remember off hand except that it was a red zone situation. The camera flashed to the sideline, and Ron was there watching the field with his normal blank look, then out of the corner of his eye, he noticed an assistant next to him working on a player's helmet. So Ron turns to him and starts to help him with the helmet. It was a critical part of the game, and yet Ron had no focus on the field action at all, to the point that he could be distracted by somebody working on a damn helmet.
We have to make a change day 1 after the season is over.
Lol at Rivera fixing a helmet. I was at the game and when Rivera walked on the field and the assistant handed him a red challenge flag to use incase he needed it during the game.. Rivera looked as though he had no idea what he was being given. Like he was being handed a bloody maxi pad and he didnt know what to do with it.
