Ordinarily, I'd say Knowshon will break the NCAA Division I-A all-time rushing record, but I do not expect him to play out his elligibility at Georgia. As a matter of fact, I expect next year to be his last. I think that from now on, the rushing record will be the domain of good-but-not-great backs who are consistent but not electrifying who need all 4 years to improve their draft status as much as possible (read people like Ricky Williams and Ron Dayne).
I think that next year, Knowshon breaks the all-time single season SEC rushing record for both yards and touchdowns, becomes the first underclassman to win the Heisman trophy, and then declares for the NFL draft.
