The beat reporter from ESPN 980, Chris Russell, got word from some within the organization who said that there was a world of difference with Grossman at the helm. There was so much better execution of the offense, a smoother calling of the plays from Kyle Shanahan to the QB -- and the efficiency with which they were communicated in the huddle, to the grasp of the plays, not having to have the play repeated from Shanahan, no awkward delays; all thanks to Grossman's superior knowledge of the offense. All luxuries that they haven't been able to enjoy all season.
Here's this from Chris Cooley:
"Rex is so fast getting in and out of the huddle," tight end Chris Cooley said. "He is so intense. There is nothing laid back. He has a quick tempo and he gets us to the ball as fast as he can get us to the ball. He called a lot of plays on first down; he called a lot of plays quick. He got to the ball when they were moving around on defense and they weren't able to make adjustments. When he finally got into a rhythm, we got into a good rhythm."
