INDIANAPOLIS - The NCAA has decided not to mess around too much with March Madness.

College sports’ largest governing body announced a 14-year, $10.8 billion deal with CBS and Turner Broadcasting on Thursday that will begin with an expanded men’s basketball tournament next March. But instead of jumping to a 96-team field, a possibility that drew criticism from bracket-obsessed fans to coaches, the NCAA plans to expand by only three teams, from 65 to 68.

Every game will be broadcast live nationally for the first time in the tournament’s 73-year history.

“It was a goal from the very, very beginning. I believe it’s what our membership wanted, and it’s what our fans wanted across the country,” NCAA interim president Jim Isch said. “I think without question, it was one of the driving factors in our position and why CBS and Turner make such great partners.”

Striking a balance was a challenge for NCAA officials.

The previous television deal, which gave CBS Sports the broadcast rights for $6 billion over 11 years, would have expired in three years. Both sides had opt-out clauses that had to be exercised by July 31, and the NCAA was preparing to do just that. The hope was to create a bidding war and strike a lucrative deal, generating more money for NCAA payouts to schools.

CBS Sports won the war, beating out at least an offer from ESPN. What’s new is that CBS will share broadcast rights with Atlanta-based Turner Broadcasting System Inc. and its stable of cable channels — TNT, TBS and truTV — from 2011 through 2024.

The NCAA won, too: Isch said the new deal will provide an average of $740 million per year that will returned to conferences and schools.

Just a few weeks ago, a much-bigger NCAA tournament seemed like it was all but a done deal.

During a news conference at the Final Four, NCAA vice president Greg Shaheen was hounded by questions about how many more classes players would miss to play in additional tourney games. College basketball analysts often called the 65-team format the perfect size, suggesting more teams would water down the tourney. Some coaches, whose jobs often hinge on tourney appearances, even rejected the notion that adding so many teams was a good thing.

Gene Smith, the Ohio State athletic director and incoming NCAA tournament committee chairman, said he was happy with the decision.

“They understood that we had a great tournament this year with high ratings and a high level of excitement,” he said. “It was thought that 96 teams would generate more money to support the NCAA’s many sports and initiatives. But we were all able to come to an understanding that gives us the support without adding that many teams.”

A 96-team field likely would have enveloped the 32-team NIT, the NCAA’s other, independently run season-ending tournament. Instead, the expansion is much more modest.

The men’s tournament hasn’t expanded since 2001 when it added one team to a 64-team field that was established in 1985.

Next Thursday, the NCAA Board of Directors can approve a plan that is likely to add three more opening round games — one in each region — to the one that has been played since 2001.

“We are very comfortable with 68, that’s what the deal is based on and it meets all our financial needs and programming needs,” said Sean McManus, president of CBS News and Sports.

The National Association of Basketball Coaches has long advocated expansion, citing the fact that while the number of Division I teams has expanded greatly over the last quarter-century.

“As coaches, we’ve been strongly in favor of expansion,” NABC executive director Jim Haney said. “I think 68 would be comfortably welcomed by all.”

But Connecticut coach Jim Calhoun said this year’s tournament, which included deep runs by Cornell, Northern Iowa, Xavier and national runner-up Butler, showed changes were unnecessary.

“I have a tough time seeing why we have to change a concept that has been so good,” Calhoun said. “This year, the parity was incredible. If you have something that has become magical and what has enhanced it is not more games, but the Butlers and the parity. Those things are what have done it. George Mason. It’s been proven time and again.”

The tourney still could go to 96 in the future.

Although Isch and Shaheen said this year’s expansion was not an indication the NCAA was already looking toward more expansion, they didn’t rule out the possibility. The broadcast deal also gives the NCAA the right to expand the field at its own discretion.

Beginning next year, every game through the second round will be shown nationally on the four networks. CBS and Turner, an entity of Time Warner Inc., will split coverage of the regional semifinal games, while CBS will retain coverage of the regional finals, the Final Four and the championship game through 2015.

Beginning in 2016, coverage of the regional finals will be split by CBS and Turner; the Final Four and the championship game will alternate every year between CBS and TBS. Under the agreement, the NCAA and CBSSports.com will again provide live streaming video of games, though Turner secured rights for any online player it develops.

The biggest winner Thursday was Turner Broadcasting.
