Greene, an all-state first team selection by the Associated Press, consistently practiced hard, and showed his ability to get through the line of scrimmage quickly.
While some coaches expressed frustration at how a few players were practicing, that wasn't the case concerning the uncommitted Greene, who is considering North Carolina State and Rutgers ahead of Alabama and Auburn.
"Our running backs coach (Bobby Saunders) tells us to finish each play,'' the 6-foot, 200-pound Greene said. "It's natural. The coach back at (Irmo) taught me that, too. Coach is enforcing that I finish every play and have the ball in the correct hand, speed through the hole, reading my linemen.
"And we've got some good linemen, too.''
The O-D game and the dead period has given Greene a chance to get away from recruiting for a few days and concentrate on practicing against some of the best high school talent in the nation.
"Competition is good. Two-a-days are bad, but competition is good,'' Greene said while chuckling. "Getting to know a lot of these guys is a lot of fun.''
Despite being hampered by an ankle injury and being limited to six games, Greene rushed for 1,367 yards and 13 touchdowns in six games.
The upgrade in competition in this week's practice has allowed Greene to gauge his playing ability, and the results are looking good.
"I'm getting a lot better,'' Greene said. "The linebackers are supposed to be playing in college, so I have to beat them to the edge, beat them to the hole.''
