There's more than just one marquee linebacker on Georgia's defense, which brings us to No. 21 in our countdown.
No. 21: Alec Ogletree, LB, Georgia, Jr.
2011 summary: A broken foot in the opener caused Ogletree to miss six games last season, but he returned to the lineup and finished with 52 total tackles, including 7.5 for loss. He also forced three fumbles and closed the season with a career-high 13 tackles, including two tackles for loss, in the Outback Bowl.
Most recent ranking: Not ranked in the 2011 postseason countdown.
Making the case for Ogletree: After starting his Georgia career as a safety, Ogletree moved to one of the inside linebacker spots last season and was a natural. At 6-3 and 232 pounds, he's a menacing tackler and can make plays sideline to sideline. Ogletree is reportedly facing a suspension to start the season, so that works against him. But there's no debating his impact on the field. He's a difference-maker against the run and the pass and has a knack for making big plays. Once he rejoined the team last season after recovering from his injury, that's when the Bulldogs really started to hit their stride defensively. Ogletree had 11 tackles in the regular-season finale against Georgia Tech and then closed the season with 13 against Michigan State in the Outback Bowl loss. The Bulldogs return one of the top defenses in the league, and Ogletree has as much pure talent as anybody who will line up on that side of the ball this season for the Bulldogs.
