You're going to hear a lot of talk over the coming weeks heading into the NFL draft about how important defensive tackles are and how rare the dominant ones are.
The recent history with defensive tackles in the Pac-10, outside of USC, of course, isn't great. Not counting the Trojans, the only conference defensive tackle picked in the first round since the 2000 draft was Oregon's Haloti Ngata in 2006.
That may change in either 2010 or 2011 with UCLA's Brian Price, a rising junior and the top returning interior defensive lineman in the conference.
Here's our list of the top returning tackles heading into spring practices, followed by notes on where each team stands at the position.
Brian Price, UCLA: 4.5 sacks, 14 tackles for a loss led all conference interior defensive linemen.
Stephen Paea, Oregon State: He's a load who's also productive, see five sacks, 11 tackles for a loss.
Lawrence Guy, Arizona State: 10 tackles for a loss as a true freshman. Hello upside.
Earl Mitchell, Arizona: 40 tackles, 5.5 for a loss after switching from H-back.
Christian Tupou, USC: Sure, he only had 12 tackles last year, but he started for the nation's best defense, which counts for a lot.
Derrick Hill, California: Mostly platooned with Mika Kane last year, but he's got the talent to break through as a junior.
Arizona: The Wildcats welcome back all five tackles listed on their 2008 depth chart and are expected to reinstate suspended former starter Lolomana Mikaele. Toss in marquee, 21-year-old JC transfer Jonathan Hollins, and the Wildcats probably have more depth at the position than any other team in the conference.
Arizona State: The biggest question is will 292-pound incoming freshman Corey Adams start beside Guy from day one. Saia Falahola and Jonathan English have both seen a lot of action, so it's not a sure thing.
California: A 3-4 defense obviously means fewer DT-types play. The question for the Bears is the pecking order behind Hill: Cody Jones and Kendrick Payne both missed last season with injuries, and is rising sophomore Trevor Guyton a big end or nose tackle?
Oregon: The interior d-line is probably the Ducks biggest question mark, seeing that both starters need to be replaced. There are high expectations for Tonio Celotto, who battled nagging injuries last year, but there is little to no experience. A pair of incoming JC tackles are expected to help immediately.
Oregon State: Paea can be a force when healthy, and there are experienced players competing to replace Pernnell Booth. The spring focus will be mostly on replacing both defensive ends.
Stanford: Brian Bulcke and Sione Fua give the Cardinal a quietly effective combination inside. They combined for seven sacks and 10 tackles for a loss. Matt Masifilo leads the depth, which will be at issue this spring. [Edit: As a reader pointed out in an email, starting DT Ekom Udofia will be back in 2009. So the Cardinal D figures to be fairly solid in the interior].
UCLA: Price will demand two blockers next year, particularly with the departure of the solid Brigham Harwell. The Bruins will be fairly experienced inside, but will any other player step forward to complement -- and take the focus off -- Price?
USC: Sure, Fili Moala is a big loss, but the Trojans will still will boast the strongest interior defensive lineup in the conference. Start with Tupou and the player he beat out in 2008, Averell Spicer. Then toss in Jurrell Casey and Armond Armstead, who both were impressive in limited action as true freshmen last year. USC actually might be STRONGER at tackle than 2008. Seriously.
Washington: Good news is just about everyone is back. Bad news is the Huskies got pushed around up the middle last year. Still, if rising sophomores Alameda Ta'amu and Senio Kelemete have big off-seasons in the weight room, they could form a solid troika with Cameron Elisara. And incoming JC transfer Johnny Tivao is listed at 5 foot 10, 350 pounds, so that's something.
Washington State: Lots of questions here for the Cougars, who will be young inside with the departure of three of their top four tackles on the season-ending depth chart. Rising junior Toby Turpin, who had 20 tackles and 3.5 tackles for a loss last year, will man one spot and Bernard Wolfgramm is the frontrunner for the other. And might the Cougs consider adopting a 3-4 scheme?
