"After discussions with Richard, his family, and our coaches I'm excited that Richard wants to make the move," Richt said. "He's one of our fastest and most powerful players, is very mature, has a strong character and is a man we can count on. I'm proud of him for always putting the team first and I look forward to seeing what he can do."
"I'm excited about the opportunity at tailback," said Samuel. "I'm ready to do anything that will help the team win."
