NASHVILLE, Tenn. -- Kyle Shurmur grabbed the snap from under center, his defensive teammates instantly bearing down on him.
Quick into Shurmur's three-step drop, two players darted toward the 6-foot-4 quarterback. Instantly, Shurmur slid to his right but not fast enough.
Throwing window all but closed, Shurmur awkwardly skipped a pass toward his receiving target just a few yards ahead. With defenders celebrating their imaginary sack, a scratchy, displeased voice boomed over the loudspeakers inside Vanderbilt's indoor practice facility.
"If you can't move out of the pocket, get off the field!" Vanderbilt coach Derek Mason's voice exploded.
