He doesn't need to RS. This was only his second year playing RB as he started as a LB in his sophomore and still played there this year. He went to Flint Northern not SW and had very little talent around him especially on his Oline yet he put up monster numbers including a 396 yard performance to break Mark Ingram's city record for rushing yards in a game (actually broke his own since he broke Ingrams the week before).
He missed 2+ games with a high ankle sprain or would have been the leading rusher in the state. The game the sprain occurred he was near 200 yards in the first half before the injury. FWIW his coach is Fred Jackson's son.
