"He is on campus and started school this past week," Butte Head Coach Jeff Jordan wrote in an email.
Garmon played as a true freshman this past fall at Iowa. He rushed 38 times for 122 yards this fall. He also caught eight passes for 57 yards.
"It was great to be a Hawkeye," Greg Garmon said in December. "Best fans in the country. It just wasn't a fit for me."
Garmon's father, Tony Hollingsworth, said at the time that he wanted his son to stay at Iowa. He said that Greg and Hawkeye Coach Kirk Ferentz agreed that Iowa wasn't a good fit for him in the end.
"He choose this move to keep his grades up and not lose a year of football," Hollingsworth said in a text message about Garmon's transfer to Butte.
"He figured a (junior) college would fit him well while staying focused on his (school) work with less distraction from a major university atmosphere during the second semester there. He felt that iowa scheme was not his style of play so this was the best move for him."
Scout.com ranked Garmon as a four-star recruit and its No. 15 running back nationally in the 2012 recruiting class. He held an impressive group of scholarship offers, including Arkansas, Florida State, Miami, Michigan and Ohio State.
