Yeah I sure would like to have an experienced play caller who has a feel for the ebb and flow of the game. But barring that, they have to put the control in the hands of Flacco.

It's one thing for a guy on the sidelines to look at a laminated sheet and call a play. It's another thing for Flacco to get everyone to the line, survey the defense, and make the call. If they're going to promote Hostler, they have to turn the reins over to Flacco IMO
