I did a little homework on this. Good defensive tackles are obviously worth their weight in gold. NFL talent at tackle is synonymous with competing at the highest level. Check out the most recent national champions, and the talent they had at the position. These are the starters for each team during their runs: 2001 Miami: Matt Walters (5th rd. 2003 draft) and Will Joseph (1st rd. 2003 draft) 2002 Ohio State: Kenny Peterson (3rd rd. 2003 draft) and Tim Anderson (3rd rd. 2004 draft) 2003 LSU: Chad Lavalais (5th rd. 2004 draft) and Kyle Williams (5th rd. 2006 draft) 2004 USC: Mike Patterson (1st rd. 2005 draft) and Shaun Cody (2nd rd. 2005 draft) 2005 Texas: Rod Wright (1st team AA, 7th rd. 2006 draft) and Frank Okam (5th rd. '08 draft) 2006 Florida: Ray Mac (3rd rd. '07 draft), Joe Cohen (4th rd. '07 draft), Steve Harris (made NFL roster) 2007 LSU: Glen Dorsey (1st rd. '08 draft) and Marlon Favorite (saw time in NFL camps) 2008 Florida: Terron Sanders and Lawrence Marsh (neither made NFL rosters) 2009 Alabama: Terrence Cody (2nd round '10 draft); backup Josh Chapman (5th rd. '12 draft), DE Brandon Deaderick is an NFL defensive tackle 2010 Auburn: Nick Fairley (1st rd. 2011 draft) and Mike Blanc (saw time in Steelers camp) 2011 Alabama: Josh Chapman (5th rd. '12 draft) and DE Jesse Williams (5th rd. 2013 draft) 2012 Alabama: Jesse Williams (5th rd. 2013 draft) So, you can see the significance of having NFL talent at the tackle position. That doesn't include the other top teams during (those who played for and lost the title game) those seasons, and the talent they possessed at the position. Alabama's defense is a bit different from some of the other groups schematically, so those numbers don't necessarily reflect the talent that they've really had across the defensive line. Essentially their ends handle a lot of the same responsibilities that tackles in a base 4-3 defense do, with pressure generally being applied from the back 7/8. Ironically, only Florida's '08 national championship team failed to produce and NFL tackle; however both Marsh and Sanders played good, hard-nosed ball for a tough defense. This season figures to be no different, with the top two teams appearing to be 'Bama and FSU, both possessing NFL prospects at the position-Jernigan almost certainly will go in the first round. We saw the devastating impact of losing Easley. We also saw the success that having great defensive tackles brought Florida last season. Unfortunately, Florida figures to be only average to above-average at the position next fall, and will be relying on a lot of young bodies to provide meaningful snaps at the position.
