I know you're trolling, but still have to respond:
What are you, blind? In this video, the ball is snapped at the 0:04 mark. Ratliff and Burlsworth make first contact at 0:05. Stoerner trips over Burlsworth's foot, or is stepped on by Burlsworth, at 0:06. Stoerner reaches out with his hand to brace himself from falling; unfortunately for him, that hand has the football, which remains on the ground.
Gravity did not cause that fumble. Burlsworth backpedaling and tripping his QB did. How much did Ratfliff contribute PHYSICALLY to that backpedal? Don't know. But mentally, 100%.
You'd have to be blind not to see that series of events.
Go Vols!
