With only a couple practices under his belt, Bullough led the Green team with 11 rushes for 48 yards.
His first carry showed signs of promise as he rushed for nine yards. His longest rush was 15 yards to average out 4.2 yards a carry.
"Riley shows the ability to play and he has [a strong] football IQ," head coach Mark Dantonio said. "He shows the ability to play on offense. He shows the ability to play on defense and he gives us a powerful punch.
"I did [think about moving Riley to offense], but I really didn't want to talk to anyone about it for the first three weeks because I wanted him to play mike linebacker. I wanted to give all the reps to our other tailbacks."
Dantonio thought Bullough had something to him while he played scout team running back.
"After watching him get ready for the Iowa game, he was the scout team tailback versus Iowa, I thought he showed he had something to him," Dantonio said. "He's used to carrying the football, he was tough and he had a little bit of something."
Bullough knows that this is a competitive sport. With him coming over on the defense it raises awareness of the other running backs.
"All the running backs are so competitive," Burlough said. "When they see another guy come in and try to take their spot it helps their game.
"It's been a great competition."
Right before the game ended, Bullough had the opportunity to play quarterback for a play. His brother, Max Bullough was put in at receiver. Max ran a crossing pattern over the middle for Riley to throw him open for a first down.
"I think they [practiced] that exactly zero time," Green team's head coach Pat Narduzzi said. "That was obviously the highlight of the day."
