OXFORD — There was something different about Ole Miss backup quarterbacks Ryan Buchanan and DeVante Kincade this week. A renewed purpose to their actions as they went through prep for the Peach Bowl.What changed? Two words: Chad Kelly. The national championship-winning juco quarterback committed to Ole Miss last week and signed with the school Wednesday, making an A and B quarterback competition into an A, B and C battle.“It definitely started a fire under them,” tight end Evan Engram said.That’s exactly what coach Hugh Freeze said he was looking for when he decided to offer Kelly a scholarship. Bo Wallace, whom Freeze recruited three years ago from the same school (East Mississippi Community College) as Kelly, will play his last game for No. 9 Ole Miss on Dec. 31 against No. 5 TCU. The ongoing competition to be his replacement for the 2015 season needed something more added to it, Freeze said he ultimately determined.“I think both of those guys (Buchan and Kincade) have bright futures,” Freeze said. “At this level, if you want to be great, you got to create competition and both have responded really well. They’re not concerned with the competition, and I don’t think Chad is either. We’ll get them all in spring and figure out what is best for our team.”There’s a lot to like about Kelly: he was a highly-recruited high school quarterback that originally landed at Clemson. When a handful of incidents led to his dismissal, he ended up where a lot of wayward football-playing youths have over the last few years, Scooba. Like Wallace and others before him, Kelly put up video game numbers at EMCC: a 66.9 percent completion rate for 3,906 yards and 47 touchdowns with eight interceptions. Kelly also ran for 446 yards and four touchdowns, and is considered more mobile out of the backfield than Wallace.But a lot of quarterbacks put up great numbers at East Mississippi, because coach Buddy Stephens recruits superior athletes and has developed a wide-open offense that plays to the fact he almost always has the most talent on the field. Wallace initially found the transition difficult, once remarking that when EMCC would face a third-and-long situation four receivers would run vertical routes and he’d throw it high and deep. That was not what he did at Ole Miss, nor is it something that has a high percentage chance of working in the Southeastern Conference.“It’s different just because down there it’s all 10 personnel (four receivers), no tight end,” Wallace said. “It’s different, especially in the run game and things like that. The screens in the run game, it’s something we didn’t do down there.”Kelly will also have one offseason to learn the entirety of Ole Miss’ offense, while Buchanan and Kincade have been immersed in it since National Signing Day 2013.Wallace said he thought that Buchanan and Kincade (both of whom will be redshirt sophomores) would both be ready to compete with Kelly (a redshirt junior), and there’s nothing that was said Wednesday by Freeze to indicate the new guy has the job won already. But with a super-talented set of receivers ready to return for 2015 (Laquon Treadwell, Evan Engram and Damore’ea Stringfellow among them), Ole Miss wanted to make sure it had the best chance at replacing Wallace.After sitting down with Kelly and deciding his past was behind him, Freeze ultimately decided to bring Kelly in.“I did my home visit with he and his family after the championship game and was convinced he was the guy we wanted to go on,” Freeze said.But if Buchanan or Kincade push through this development, come out firing in the spring and take a hold of the job, then it’s still worth it if this December addition played any part in further motivating them.
