While many eyes will be on Florida as it looks to replace Tim Tebow, I am more interested in what is going on at Georgia. This is a huge season for Bulldogs coach Mark Richt. He overhauled his defensive staff, canning coordinator Willie Martinez, ends coach Jon Fabris and linebackers coach John Jancek, and hired Dallas Cowboys assistant Todd Grantham as coordinator, Warren Belin as linebackers coach and Scott Lakatos as secondary coach. The lone holdover on the defensive staff is line coach Rodney Garner. Grantham is the key guy: He arrives with an extensive NFL background and will install a 3-4 defense. Will the players adapt quickly? The offense also has issues as it looks for a quarterback. It’s a three-man race between Logan Gray and redshirt freshmen Aaron Murray and Zach Mettenberger. This is Richt’s biggest spring in Athens.
