Do CJ, Greene have upside?

Shonn Greene made his long-awaited return to game action in Week 7 against the San Francisco 49ers, though you wouldn't know it from the stat sheet. He was only on the field for two snaps and had just one carry for two yards. It's hardly a surprise that the short-yardage, goal-line specialist didn't see much action, since the Titans were playing from behind, only rushed 13 times as a team and didn't have any goal-line situations.
