We see it all the time, most football coaches are terrible game managers. Guys like Mike Smith, Les Miles, Mike Leach are great football minds and great with the Xs and Os, but dunces when it comes to managing the game. Like it or not but guys like Belichick and Chip Kelly are good at this. They know when to go for it, when to go for 2, don't waste timeouts, and put the other team in tough spots.
