Raanan's 2011 Power Rankings: Top Coaches

Eight years and just two winning seasons. Lewis also has knack for compounding losses by taking shots at his players in the media. That's not a winning philosophy. (AP Photo/Al Behrman)

The Best and Wor... By Jordan Raanan, Xfinity.com Sports

In no sport is coaching more important than football. That's why it's imperative to have the right man running the show in the NFL.

So who would be the right man for me if I owned a team? Right now, here's my breakdown for this upcoming season. (AP Photo/Winslow Townson)

26-32 The First-... The jury is still out on Jim Harbaugh, Leslie Frazier, Mike Munchak, Ron Rivera, Pat Shurmur Hue Jackson and even Jason Garrett. All will be spending their first full season as the head boss. Even I am willing to give a guy a full season before I judge him. (AP Photo/Paul Sakuma)

25. Norv Turner Turner has wasted tons of talent in San Diego, this after unsuccessful runs in Oakland and Washington. Wouldn't trust him to pick out my wardrobe. And I dress like a sportswriter. (AP Photo/Chris Carlson)

24. Chan Gailey There's a reason he went 11 years between NFL head coaching jobs: he's not very good at it. Good assistant coach. (AP Photo/Charles Rex Arbogast)

23. Gary Kubiak His teams consistently underachieve. And there doesn't appear to be a coach out there that knows as little about defense than Kubiak. (AP Photo/Jack Dempsey)

20. Jim Schwartz... He could make a huge jump by this time next year. His energy is infectious. It's why the Lions are finally headed in the right direction. (AP Photo/Han Deryk)

19. Tony Sparano... The Dolphins would have fired him if Jim Harbaugh didn't rebuff their offers. Gimmicks (the Wildcat) only work for a second in the NFL. (AP Photo/David Manning)

17. Pete Carroll... As a college coach, he's among the best ever. As an NFL coach, he's average, as evidenced by a 40-40 career record. (AP Photo/Elaine Thompson)

13. John Fox Nobody would have won in that situation last season in Carolina. Might as well delete it from his resume. He's had some good seasons, and would have a Super Bowl if not for Tom Brady. (AP Photo/Ed Andrieski)

3. Mike Tomlin He's not the tactical genius like some of the other top coaches. But he doesn't have to be with Dick Lebeau running his defense. Still, there may be no better manager of men in the business. (AP Photo/Cliff Owen)

1. Bill Belichic... Easy choice. He's the best game-planner year after year. Having the league's top quarterback commanding your offense doesn't hurt, either. (AP Photo/Winslow Townson)
