Not that a former walk-on at A-Back making a big impact is anything new at Georgia Tech, to be fair.
In 2011, Georgia Tech's A-Back rotation consisted primarily of seniors Roddy Jones and Embry Peeples along with junior Orwin Smith -- the trio combined for 165 carries on the year, and the leader after that was redshirt freshman Tony Zenon with 15 attempts. With the graduation of Jones and Peeples, there was a lot of concern and confusion over who would be filling that role -- BJ Bostic missed 2011 with a broken arm, and Zenon and Deon Hill were coming off their first non-redshirt season at the college level.
