LOUISVILLE, Ky. — Back in November, when Creighton set out for the Maui Invitational, the Bluejays stopped in San Diego and the next day shared a charter jet with the San Diego State team on their flight to Hawaii. Memories of Creighton’s overtime win over San Diego State in the first round of the men’s N.C.A.A. tournament the previous March might have led to some awkward moments.
But the two coaches, Greg McDermott of Creighton and Brian Dutcher of San Diego State, sat across the aisle from each other, poring over film on their laptops, trading scouting reports and ruminating about the possibility of playing each other again in the early-season tournament.
They did not, at least then. And when the teams flew back to San Diego, dropping the Aztecs off, the coaches — and their teams — bid each other adieu.
See you down the road.
That meandering road carried both teams here, to a place they had never been before, a regional championship in which the coaches and players — including a pair of brothers, Creighton’s Arthur Kaluma and San Diego State’s Adam Seiko — marveled at the serendipity of it all.
“I never thought we’d be playing them here or I would have tried to steal a few play calls off his computer,” Dutcher mused.
The next time the two coaches get together, they’ll have plenty more to discuss after San Diego State rallied for a 57-56 victory on Darrion Trammell’s free throw with 1.2 seconds left, in a game that was so thick with turns and tension that it did not end until well after what turned out to be the final buzzer.
San Diego State, which had only twice before been to the second weekend of the N.C.A.A. tournament, will play Florida Atlantic, the champion of the East Region, on Saturday with a berth in the national championship game on the line.
The deciding play came as San Diego State ran the clock down for the final shot.
Trammell drove to the lane with Ryan Nembhard on his right hip and let loose a floater that just grazed the rim as the buzzer sounded. But rising above the cacophony, as Trammell lay on the court, was the whistle of the referee Lee Cassell.
Soon, Trammell went to the foul line with the crowd on its feet, four teammates behind him — and the entire Aztecs bench — locking arms. Trammell’s first free throw rolled off the rim, and the crowd’s roar grew even louder.
He took two dribbles and swished the next one.
Baylor Scheierman, who played quarterback in high school, inbounded the ball and threw a long pass toward Kaluma and San Diego State’s Aguek Arop near the other endline. They tipped the ball out of bounds as the buzzer sounded. The officials, though, waved both teams back to their benches and reviewed the play to see who had touched the ball last and whether there was any time left.
After a few minutes, they ruled that time had expired. San Diego State players sprinted onto the court to celebrate.
San Diego State guard Lamont Butler had 18 points on 8 of 11 shooting, and was set to take the final shot until Creighton fouled him with six seconds left, forcing the Aztecs to take the ball out of bounds but also resetting the shot clock.
Trammell, a transfer from Seattle University who had scored 21 points to help carry San Diego State to an upset of top-seeded Alabama on Friday, had made only 5 of his 14 shot attempts and had not been to the free-throw line until the final second.
The game unfolded as a contrast of styles, Creighton’s artful, free-flowing offense finding its way against San Diego State’s muscular, methodical brand of basketball.
The game was played largely at San Diego State’s preferred pace, but Creighton played almost exclusively with the lead, fending off repeated Aztec charges.
After Creighton surged to a 28-20 lead, urged on by a largely blue-clad crowd, San Diego State finally figured out how to keep the Bluejays’ 7-foot-1 center, Ryan Kalkbrenner, from having his way diving to the rim for alley-oops or putting his nifty post moves to use. Nathan Mensah, San Diego State’s 6-foot-10 senior center, did yeoman’s work against Kalkbrenner, who led Creighton with 17 points.
When Trammell sank a jumper near the free-throw line, San Diego State had finally gotten even with less than three minutes left in the half. But Creighton didn’t allow another basket and carried a 33-28 lead into the break.
San Diego State came storming out of the locker room, and when Mensah blocked consecutive shot attempts, sparking a fast-break lay-in by Butler, the Aztecs had their first lead, 35-34.
Again, it did not last long. Kaluma answered with a driving layup and San Diego State went cold, missing its next 10 shots — many of them on drives to the rim.
The parents of Kaluma and Seiko, along with their two young sisters, sat a few rows up at center court wearing customized white T-shirts with a basketball, both schools’ logos and the names and numbers of the brothers.
When the game was over, their two sons exchanged a hug in the handshake line, acting as exemplars for their teams, one of which cut down the nets while the other felt like it had its hearts cut out.
