When it came down to the SWC championship game, size mattered most against the ND-Fairfield boys basketball team.

Immaculate's low post advantage, keyed by five players at 6-3 or taller, and SWC tournament MVP Daniel McCorkle helped the Mustangs overcome a big first half deficit en route to a 64-53 win over ND on Thursday at Weston High School.

"They're a great team," Lancers guard Dan Upchurch said of Immaculate. "They've got some big guys and their guards are tough."

The Mustangs trailed by as many as 13 in the first quarter, but with help of McCorkle's 17 points that included 11 free throws, scratched back into the game. He also distributed the ball to Immaculate's big men-- Vitor Melo, Sheldon Irving, Brian Hatcher and Felipe Teixeira-- as the quartet, three of whom are seniors, combined for 28 points.

"They have great size and they're mostly seniors," ND coach Vin Laczkoski said.

ND built a 19-6 lead midway through the first with help from Earl Coleman and Upchurch. Coleman scored a game-high 21, and Upchurch added 14 for ND.

"We were pushing the tempo," Upchurch said.

But Marcos DeOliviera's buzzer-beater at the end of the first cut ND's lead to 11-point lead to just 21-13. The Mustangs outscored ND 51-32 after DeOliviera's quarter-capper, and 38-21 in the second half.

"We turned the ball over too much," Upchurch said. "In the second half they dropped into a matchup zone and it was hard."

"We had a hell of a first half, but the second half wasn't too great," Laczkoski said. "And that's because Immaculate took us out of a lot of things."

Laczkoski-- despite finishing second for the second time in four years-- was not upset.

"Out of 15 teams, you don't want to come in second, but it's a lot better than eighth or ninth," he said. "This is already on the back burner."

The Lancers will now set their sights on the elusive Class M championship. Notre Dame has never won the state crown, twice falling in the state championship game. ND has not reached the title contest since 1980.

"We'll re-group and get ready for states," Laczkoski said. "We put ourselves in a good position. But, as you know, it's one-and-done."

The Class M tournament lacks the ferocity of Trinity Catholic and Career Magnet, both of whom moved up to Class L. However, undefeated Enfield lurks as the top-seed, fresh off its North Central Connecticut Conference championship.

Upchurch referenced the 2011 St. Joseph team, which lost in the FCIAC quarterfinals but went on to win the Class LL championship.

"St. Joes did it last year," Upchurch said. "We're just going to take all of our anger out on those teams."
