With Alabama drawing the Rivals.com No.1-ranked signing class in the nation last February, anticipation runs high among fans waiting to see how an especially gifted group of newcomers melds with a group of veterans with some obvious depth concerns. BamaOnLine.com presents a daily countdown of 10 signees - published in ascending order - who could have the most impact on the 2009 season. The listing is influenced by the Crimson Tide's depth at the positions the signees are expected to play, not just their prep credentials. Note: Because they had not yet qualified at the time this series launched, signees Eddie Lacy and Darrington Sentimore were not considered.

Position: Offensive line.

Size: 6-2, 330 pounds.

High school: Atlanta Westlake.

The film room: Rivals.com's video on Warmack provides one reel of his playing tackle and another at guard, which provides an easy way to see both his skill on the outside and his power on the inside. He is quick off the ball, sustains blocks well, and moves well enough to reach linebackers and even a safety or two. For a prospect who weighs 330 pounds, Warmack moves amazingly well. As tough as it is to judge him against high school competition, it is evident he has the athleticism for the college game.

The money clip: On the very first play of Warmack's video at tackle, he takes out two defenders on a sweep right, including a vicious pancake – see this play at the 0:07 mark.

Who is in front of him: For much of the spring, sophomore John Michael Boswell worked at the right guard position ahead of Warmack. Boswell played at tackle on A-Day, however, with Brian Motley seeing some action at right guard. David Ross could also figure into the competition there.

Climbing the depth chart: Warmack quickly established himself with the second group on the offensive line in spring drills as an early-enrolling true freshman. He drew praise from head coach Nick Saban several times, particularly for his run blocking skills, and saw plenty of action on A-Day. While Boswell played tackle on A-Day, he was at guard for the majority of spring practice and the guess here is that he'll be back at guard when fall camp commences. The UA staff looked at several options at right guard in the spring, and there is limited experience among all the candidates. That bodes well for Warmack, as does the head start he got as an early enroller. If he maintains his place on the second unit, he'll be just one injury away from starting, which is more than the other incoming freshman can say entering fall camp.

What will make it tough: Pass blocking isn't as tough at guard as it is at tackle, but it's still a crucial part of Warmack's development that may prevent him from ascending any higher on the depth chart in the short-term. With a new starting center to the left of whoever wins the right guard job, the inside gap will be one that defenses may try to exploit early and often this season. … As physically developed as he may be, it's easy to overlook the fact that he was playing high school ball just last year. The early returns on Warmack are very encouraging, but there is still much to learn.

Shane Youngblood's take: "Warmack is physically almost the perfect guard. He is strong as a bull, compact and has good feet for a big man. He wasn't asked to pull or trap a lot at Westlake High School, so there will be a learning curve there. What he does best, however, is get his large hands up under his opponents's shoulder pads and drive his man backwards. He is almost a clone of former Tide guard Marlon Davis except Warmack is a more powerful kid at the same stage."
