I'll say this about Bill B. With 9:40 left in the game, down 28-9 and facing 4th and goal from the 15 Bill sent in the FG team to make it a 16pt game. Which is absolutely the right call. Still need two scores and a couple 2 point conversions but you can't give away those points. How many coaches in that situation hit the panic button and go for it? Bill never panics. It seems like he's always in total control during the game. He doesn't always win. But he always seems to make calculated decisions that are almost always the right choice.
Theres been much said of his mysterious data/analyst/numbers/statistical/probability guru that's almost never seen but is always in his ear. I'm not sure if that guy has a direct line to Bill during games but it wouldn't surprise me.
