Agreed, but that's assuming Shula is "sharp". And he hasn't been an OC or HC for a while.
Hopefully, he will be. However past experiences has shown he's been a not so great play caller. And who's to say what he'll do during a game, especially an important one??
Just look at the 'innovative', celebrated Chud for example, and all the bone head moves/plays he did this past season as an OC and play caller. I get your point though.
It is amazing that Shula has stayed employed every single year of his career considering how dumb some of you guys seem to think he is. Apparently all of these coaches are even less "sharp" for hiring him year in and year out, whether it is to be OC or as QB coach.
