The first play of the fourth quarter may have turned everything around. In a bad way for South Carolina.

A tipped pass and interception was returned 54 yards by Florida defensive end Justin Trattou, the 265-pounder lumbering with his blockers.

A few plays later, Florida capitalized, and it’s now ahead 24-14.

Up until that pick, USC had yet to commit the game-changing mistake. It did fumble it over at midfield, but survived that second-quarter mistake.

This time …

The few seconds after the play were telling:

Stephen Garcia looked longingly downfield, then was met on the sideline by Steve Spurrier. The two exchanged a few words, then Spurrier gave Garcia over to quarterbacks coach G.A. Mangus, presumably to take over the good-cop routine.

Then Spurrier bent over at the 36, his head in his hand, remaining in that position for about 15 seconds. Then he stood up and picked up his play sheet.

Spurrier knew the implications. Instead of at least a field goal try, meaning a tie game or a shot at the lead, Florida now has a two-score lead – and the momentum back.

What a turn.
