Sometimes a coach inherits a bad team or steps into a program where the university simply does not invest in basketball. In some cases, through recruiting, Xs and Os and inspiration, that coach can turn a bad team into a good or even great one.

The guys on this list are not those coaches. Here are the 20 worst coaching tenures in the six major conference since the NCAA Tournament expanded in 1985.

With 347 Division I teams, following college basketball can be overwhelming. Let Athlon Sports start your college hoops week each Monday with a look at some of the most intriguing, most important and most interesting stats from around the sport:

The final two undefeated SEC teams watched their unblemished records fall during their trips out West. Florida lost 65-64 to Arizona while LSU lost 89-70 at Boise State.

Despite the loss, the Gators, who led until the final seconds, appear to be the class of the conference. Unfortunately for the SEC, standing out is not hard to do. Beyond the top four or five teams, the SEC may struggle to fill postseason spots.

The Big 12 may be one of the most interesting leagues from top to bottom in 2012-13, but the smart pick at the top remains, as always, Kansas.

The Jayhawks have won at least a share of the last eight Big 12 regular season titles, including the last four outright. Thomas Robinson is gone from Lawrence, but Bill Self again has stars ready to emerge.

Athlon Sports continues its countdown to the start of the 2012-13 basketball season, which begins with the first games on Nov. 9, with a countdown of the nation’s top conferences. We will release one conference preview each day, counting down to the top conference.

LSU hasn’t quite been as formidable as we originally thought, but Alabama’s trip to Baton Rouge to battle the Tigers is still the biggest game in the SEC this season. There’s also an intriguing battle in Starkville, as Mississippi State hosts Texas A&M in a game featuring teams jockeying for position in the SEC West. Georgia is two wins away from wrapping up the SEC East title. This week, the Bulldogs host the improved Ole Miss Rebels.

A season can be changed by an injury. In the same way, 10 teams are hoping a key player returning from injury will change their fortunes for 2012-13.

Among those players returning from injury include a forward with All-American potential at Minnesota, a key veteran at rebuilding North Carolina, and explosive guard at USC and former starters at three SEC schools.

When SEC basketball coaches get together for media days or other offseason events, they may need name tags.

One of the unfortunate truths of the latest wave of conference realignment is the overwhelming focus on football.

As a result, basketball and other sports have been of secondary concern in some circles. In others, such as at Butler and VCU and in the Horizon, Colonial and Ohio Valley, basketball is the primary engine of revenue. Almost every league in some way has been impacted by the dominoes of realignment.
