Unnecessary, Intentional Roughness

On Florida's first play of the second half, Leak threw the ball away over the head of the Florida FB. It was obviously uncatchable. Thus, there was no infraction called for pass interference. But, why did the Ohio State defender run over the "intended receiver"? Why is contact allowed in such instances where it is obviously unnecessary. If the ball is so poorly thrown that the officials determine it to be uncatchable, the defender should be able to make the same determination and at least minimize contact. Or, the officials should make the correct call and flag them for a personal foul.
