Neither was McDaniels. Gotta get someone, at least for a year, and Venturi knows football like no other coach that I have listened to. Look at who we've had. Caldwell, Pagano. Both horrible at even discussing the game or strategy.
Venturi knows the Colts players' strengths and weaknesses very well. Not only is he great after the fact, as you say, but he always comes up with a game plan in advance, based on the next opponents strengths and weaknesses. Not sure Pagano could.
