The Canes signed two in the 2012 class -- five-star Duke Johnson and three-star Danny Dillard. Both are expected to enroll this summer. Dillard is a redshirt candidate, while Johnson is expected to play a major role in the offense this coming season.
The Hurricanes seem to want two running backs in the 2013 class and they already have one committed -- South Plantation's Alex Collins.
At 5-foot-11 and 195 pounds, Collins missed his entire sophomore season due to being ineligible but really put his name on the recruiting map as a junior. He was, by far, the leading rusher in Broward County in 2011 and brings a lot to the table as a prospect. He has the size and toughness to go inside and he has the home run speed to make things happen on the perimeter. He's one of the state's premier running backs in the 2013 class and is solidly committed to the Canes. He grew up dreaming of playing at UM one day.
The second running back is wide open, it seems. Ryan Green (St Pete Catholic) landed an early offer from the Hurricanes and seems like the in-state back being recruited the hardest by Miami right now. At 5-foot-10 and 185 pounds, Green has tremendous speed and quickness and brings a lot of versatility to the position. He has Miami in his top five (along with Florida, FSU, Notre Dame, and USC). Green visited Miami for one of their Junior Day events back in January and plans to take a return trip at some point. He hasn't singled out a favorite yet and is still trying to see some of his top choices so it's still early. Green is already listed as a four-star prospect on Scout.
The top out-of-state target appears to be Derrick Green from Virginia. At 5-foot-11 and 220 pounds, he's a bruiser inside but has tremendous speed as well. His size/speed combination, coupled with his production numbers on the field, have made him one of the nation's most heavily recruited running backs. Miami, along with about two dozen other schools, have already offered. He has mentioned a few times his desire to eventually make a visit to Miami but it may be tough getting him to come this far from home. Ohio State is the out of state school that he seems to have the most interest in right now.
More running back prospects will emerge down the road but those are the three who seem to sit somewhere near the top of Miami's recruiting board at this time.
