Former Iowa running back Adam Robinson wants to rejoin the team. Robinson apologized to friends, family and former teammates for breaking team rules and Iowa law by possessing marijuana at a news conference in Des Moines on Sunday. "I know I have disappointed you and let you down," Robinson said. "For that, I am sorry." Robinson, 21, was charged with possession of marijuana Dec. 27. Iowa coach Kirk Ferentz suspended Robinson for the Dec. 28 Insight Bowl. Ferentz kicked Robinson off the team Jan. 3. Robinson said Sunday the dismissal was for academic problems.
