ANN ARBOR, Mich. (AP) - Running backs Derrick Green and De'Veon Smith signed with Michigan on Wednesday, giving the Wolverines a pair of additional options in the backfield.

The 5-foot-11, 220-pound Green is the nation's top-ranked running back recruit, according to Scout.com. The Richmond, Va., product scored over 20 touchdowns as both a junior and a senior in high school.

Smith, who is from Warren, Ohio, is the same height and almost the same weight as Green. He ran for 6,750 yards in his high school career.

Michigan announced a class of 27 signees.

Michigan's leading rusher last season - by far - was quarterback Denard Robinson. His college career is now over, and running back Fitzgerald Toussaint is recovering after breaking his left leg in mid-November.
