Before the real madness of March gets underway with the annual NCAA Tournament for men’s basketball, Championship Week takes center stage with all the season-ending conference tournaments. The winner of these single-elimination contests earns an automatic berth into the 68-team field for the Big Dance the second half of March.

BetOnline is one of the top-rated online sportsbooks for betting college basketball. Heading into this week’s action, it is time to find the best value on the board to win two of the most popular college basketball conferences: The ACC and Big 12.

ACC Tournament Betting Odds

The ACC is coming off one of its more disappointing performances in the regular season. The AP’s latest Top 25 only has four of the possible 14 ACC teams on the list. The postseason is a second chance to prove that this is the premier basketball conference in Division 1 play.

Leading the way are the No. 4 Florida State Seminoles after winning the ACC regular-season title at 16-4 in conference play. They opened as +175 favorites to also win the conference tournament, but the current odds have moved to +200. Florida State has some solid momentum with six wins in its last seven games after losing to Duke on the road in early February.

The No. 10 Blue Devils opened as +200 second-favorites. Those odds have moved to +160 as new favorites to win based on the early money coming in. The quick downward move only drains more value, given their current odds. There has to be some genuine concern with a 3-3 record in their last six games that includes bad losses to NC State and Wake Forest.

Louisville is ranked No. 15 in the nation with +300 odds to win this week’s competition. This is another ACC team that that struggled down the stretch with four losses in its last seven games.

The top-valued pick in this conference would be the No. 17 Virginia Cavaliers at +550. The defending national champions hardly looked the part for most of the season, but they bring an eight-game winning streak into this tournament, including victories against Duke and Louisville.

I am sticking with the Cavaliers as the hottest team at the best odds.

Big 12 Tournament Betting Odds

The No. 5 Baylor Bears were the biggest story in the Big 12 for most of the season, but heading into this week’s tournament, all eyes are on the No. 1 Kansas Jayhawks as the early team to beat in the NCAA Tournament betting futures.

Kansas is the clear -125 favorite to add a conference tournament title to its first-place finish in the regular-season standings. The Jayhawks went on a 16-0 run to close out the regular season. This impressive performance includes a road win over Baylor on Feb. 22 to avenge an earlier home loss to the Bears on Jan. 11. All the momentum has swung towards Kansas playing its best ball of the year.

Baylor ran its winning streak to 23 games before the loss to Kansas. Since that point, it also lost to TCU and West Virginia in a much shorter five-game span. The Bears would have to be considered a value pick as +200 second-favorites to win the Big 12 Tournament. Yet, I doubt it makes all that much sense betting against the Jayhawks right now.

The rubber match in the conference championship game would be instant 'must-watch TV,' but I am sticking with Kansas.

The No. 22 West Virginia Mountaineers are the only other nationally ranked team in the Big 12. Their odds to win are +800 after the Texas Tech Red Raiders as +600 third-favorites.

Unfortunately, the gap between the top two favorites on the list and these two contenders drains most of the betting value in their long odds.
