He returned two fumbles for touchdowns, posted 5 total tackles, and had two pass deflections. The two touchdowns on fumble returns tied an NCAA record. After two stellar years at defensive end, Norwood moved to Linebacker for his Junior season in 2008.

In addition, Norwood broke South Carolina's all-time sack record by dropping Jevan Snead for a 5-yard loss during the Gamecocks 16-10 victory over Ole Miss. The record was previously held by defensive tackleAndrew Provence who had 26 career sacks. For the 2009 season, Norwood posted 81 tackles, 7.0 sacks, 11 quarterback hurries, 3 blocked kicks, a forced fumble, and a fumble recovery.
