Iowa State came back after making less than a third of its shots in the first half, improving to 50 percent in the second half, including 6 of 13 3-pointers (46.2 percent).
"In the first half we were a little stagnant on offense, guys were shooting shots, not running back and we weren't as hungry as we were in the first half as we were in the second half," Kane said. "(Boise State) came out really aggressive and they got up big on us."
Kane put Iowa State within a point about 6 minutes into the second half. Kane took two dribbles with his right hand near the top of the key, then hit a jumper and was fouled. He missed a free throw to tie, but Ejim pulled down the rebound and hit a layup to give the Cyclones their first lead of the game.
Marks tied it at 60 with a jumper and a 3-pointer on consecutive possessions, but Iowa State responded with two free throws and a straightaway 3-pointer by Kane with less than 2 minutes left.
Boise State coach Leon Rice said there's a reason Iowa State is undefeated.
"Nobody's been able to do it and I think we did a great job both offensively and defensively," he said. "We had a chance to be there at the end and that's what we wanted, but they know how to make plays, they know how to win games and there's a reason they're undefeated."
Kane, Ejim and Georges Niang were selected to the tournament's all-tournament team, winning trophies etched in paddles for canoes or paddle surfing. Anthony Drmic made the all-tournament team for Boise State.
