What was obvious midway through the season became official today, as Iowa running back Shonn Greene told ESPN's Joe Schad he will forgo his senior season and enter the NFL draft.
The Doak Walker Award winner eclipsed 100 rushing yards in all 13 games this season and set a single-season Iowa rushing record with 1,850 yards. Greene is projected to be the third or fourth running back selected in April's draft, provided two other junior stars, Ohio State's Chris "Beanie" Wells and Georgia's Knowshon Moreno, also come out early.
At 23 years old, Greene clearly made the right decision here. Though Iowa will be strong next season, he doesn't have much left to prove and needs to start making money while he's still relatively young (in athlete years).
Freshman Jewel Hampton, who had 55 rushing yards in the Outback Bowl, will enter next season as the front-runner for the starting running back spot.
