Logan started alongside the last big thing among LSU defensive tackles -- Michael Brockers -- in 2011, posting 57 tackles, including 6.5 tackles for loss and three sacks while starting 13 of 14 games. It was a terrific breakout performance for the long-armed and stout defender, as he'd only posted five combined tackles in 2010 after redshirting in 2009.
With Brockers being selected by the St. Louis Rams in the first round a year ago, Logan became the focus of opponents' interior blocking in 2012. As a result his statistics slipped a bit. He posted 45 tackles, 5.5 tackles for loss, two sacks and two forced fumbles. The production was enough to earn him Second Team All-SEC by the Associated Press.
As an indication of Logan's work ethic, he was given the honor of wearing No. 18 this season after wearing No. 93 previously in his career. Wearing the No. 18 is a tradition that dates back to quarterback Matt Mauck, who wore the number and helped guide LSU to a championship back in 2003.
The number has been passed down through various players since, including former running back Jacob Hester. Last year it was worn by strong safety Brandon Taylor (third round pick by the San Diego Chargers), who despite earning less fanfare than the others starting in LSU's fine secondary was generally credited with being the leader of the deep patrol.
Overshadowed a bit by LSU's dynamic duo of Barkevious Mingo and Sam Montgomery on the outside, Logan was quietly the Tigers' most consistent defensive lineman in 2012.
WEAKNESSES: Didn't take the step in his development in 2012 that scouts had hoped to see from him. Doesn't use his swim move often enough, simply resorting to his bull-rush, which decreases in effectiveness as he tires and loses his pad level. Gets caught up in the hand to hand combat at the line of scrimmage and loses track of the ball.
Plays with a high-motor but too often relies on his effort to make plays when his initial burst or push doesn't work, showing few complementary moves for a player with his experience. Frequently is substituted as part of LSU's rotation, which raises concerns about his readiness to play consistent snaps against even better competition in the NFL.
Compares to: Brodrick Bunkley, DT, New Orleans Saints -- Just as it was for Bunkley when leaving Florida State seven years ago, the talent is in Logan to develop into a legitimate NFL starter and perhaps even turn into a standout. To do so, however, he'll need to develop a greater array of pass rush moves. Otherwise, his strength and effort should be enough to help him carve out a niche as a solid run-stuffing presence in the middle.
