Okay, so allow me to explain how football works in a way I'm hoping you guys can understand:
a. College coaches spend the off-season figuring out who the best players are. Come the season, they put those players on the field. Then, the coaches (at least, this is true of the best coaches) call plays that they know those players can execute successfully. That means they're not using the entire playbook, just the parts that fit the lads and the opponent. Therefore, this year's play calling will look different than last year's play calling, because this year's starters are different than last year's.
b. Regardless of what Volador might think he read on these boards, pretty much everyone here knows who's running our offense: it's Josh Heupel. He's on the intercom, and at times where he's not calling the plays himself, he listens to his OC dial up each play, and he interjects if he thinks some other play would work better. On top of that, he's guiding the OC and DC with his strategic direction, before and throughout the game. So whether Joey Halzle or Josh Heupel speaks the words, it is Josh's show. 100%.
c. In Josh Heupel's offense, spread formations and the passing game exist to set up conditions for the run. We are a running team, somewhat more than a passing team. That was true last year with Hendon Hooker at QB, it was true this season with Joe Milton at QB, and it will be true next year with Nico Iamaleava at QB. The specific plays called reflect the abilities of each of those players, as well as the other fellas on the field, but we will remain a team where the pass (and spread) sets up the run.
So I hope that soothes all your confusion. It all makes perfect sense once you know these things.
Go Vols!
