We continue our preseason power rankings at each position with offensive coordinators.
One thing to note about offensive coordinators: There are numerous head coaches who oversee their offenses, and we do not rank those guys on this list.
You can check out our post-spring practice power rankings here. We will update the power rankings each week during the regular season and release the final rankings for the season after the BCS title game.
The rating of a player and coach can fluctuate each week during the season depending on how they fared the previous week, but the power rankings measure overall career performances as well as their most recent results.
OFFENSIVE COORDINATOR POWER RANKINGS
1. Kevin Wilson, Oklahoma BUZZ: He oversaw an offense that scored a record number of points last season, and he has his quarterback, two 1,000-yard running backs and the best tight end in the nation returning this season.
2. Galen Hall, Penn State BUZZ: Hall is a veteran assistant who has seen it all. He deserves kudos for helping Joe Paterno ? his college coach, by the way ? see the light and upgrading the Nittany Lions' offense the past few seasons.
3. Gary Crowton, LSU BUZZ: He has a long track record of success, and it was his offense that led the way when the Tigers won the national title in 2007.
4. Norm Chow, UCLA BUZZ: Here's another guy with a long track record. Don't hold last season's inept Bruins offense against him. An offensive staff of Bill Walsh, Sid Gillman and Don Coryell couldn't have done anything with what Chow had to work with.
5. Shawn Watson, Nebraska BUZZ: He's underrated nationally and has overseen some potent units of late. It wasn't bad offenses that got Bill Callahan run out of Lincoln.
6. Andy Ludwig, California BUZZ: Ludwig is in his first season with the Golden Bears. He had the magic touch last season with unbeaten Utah, pushing all the right buttons for the Utes.
7. Greg Davis, Texas BUZZ: This guy has been a frequent target of derision, but he deserves credit for the work he has done of late. The Longhorns had no running back to rely on last season, but Davis still put a potent unit on the field every week. He works well with QB Colt McCoy.
8. Sonny Dykes, Arizona BUZZ: His dad, Spike, was an offensive innovator when he was coach at Texas Tech. Sonny also is a former assistant to Mike Leach at Texas Tech. He will have his work cut out for him this season with an untested quarterback.
9. Dana Holgorsen, Houston BUZZ: He's a rising star and a guy to keep an eye on. Houston was magnificent offensively last season and should be so again. Art Briles oversaw a powerful offense when he was Houston's coach, and after he left, Holgorsen made some tweaks and revved it up even more.
10. Mike Bobo, Georgia BUZZ: Bobo has guided some strong units in his time in Athens. He's good at matching his season philosophies with the talent he has on hand. Last season, he had Matthew Stafford and Knowshown Moreno. This season, it's Joe Cox and Richard Samuel. Watch the numbers end up being close to the same.
11. Ed Warriner, Kansas BUZZ: While he cut his teeth as a running-game assistant, he has done great work with Kansas' high-powered passing attack. Todd Reesing has blossomed under Warriner's tutelage.
12. Gus Malzahn, Auburn BUZZ: The pressure is on Malzahn this season. His offenses the past two seasons at Tulsa were highly productive on the ground and through the air. But does he have the talent he needs at Auburn to truly run his offense? It doesn't appear that way.
13. Jim McElwain, Alabama BUZZ: Before he moved on to Alabama, McElwain did solid work for Pat Hill at Fresno State. He understands what Nick Saban wants, and that's a mistake-free, power-running attack. McElwain faces a big test this season because of an overhauled offensive line and a new quarterback.
14. Robert Anae, BYU BUZZ: Anae does good work - albeit somewhat in the shadows ? with an offense that's usually one of the most productive in the nation. He does an excellent job of making sure hi quarterbacks spread the wealth.
15. Bryan Harsin, Boise State BUZZ: He was promoted when Chris Petersen was promoted to coach, and they continue to oversee diverse offenses. Two years ago, Boise was a run-first team. Last season, with redshirt freshman QB Kellen Moore, the Broncos reverted to their days as a "let's throw it around" team, and the move went off without a hitch.
16. Danny Langsdorf, Oregon State BUZZ: Langsdorf is another assistant who toils in anonymity on the West Coast. He never has top-flight talent, but always seems to find a way to get the job done. His offenses usually are excellent on the ground; just look at all the 1,000-yard rushers the Beavers have had of late.
17. Jimbo Fisher, Florida State BUZZ: He is FSU's coach-in-waiting, and it seems likely he'll be in charge by the 2011 season. He's under a little bit of pressure this season. The FSU offensive line is a team strength for the first time in a while, and Fisher needs to make sure the running game produces while also upgrading what has been a mediocre passing attack.
18. Mike Schultz, Illinois BUZZ: He moves from TCUto the Illini, and his run-first attitude should help QB Juice Williams. Schultz did nice work at TCU, and a revamped offensive staff at Illinois has some work to do ramping up the Illini's ground game.
19. Mike Bajakian, Central Michigan BUZZ: The Chippewas are fun to watch offensively, and Bajakian deserves credit for overseeing an exciting bunch. He built on the tenets of previous coach Brian Kelly and has made Dan LeFevour one of the most dangerous quarterbacks in the nation.
20. Paul Chryst, Wisconsin BUZZ: This guy deserves more credit. He seemingly always has less-than-stellar quarterbacks, but despite opponents knowing what's coming, the Badgers still are able to line up and run the ball effectively. If Wisconsin ever could become truly diversified on offense, maybe Chryst would get more national notice.
