Motum finished with 23 points in 37 minutes, the last 11 of which came in on a trio of threes and two crucial free throws in the final five minutes.
Olynyk did all his damage in the second half, dropping 22 points on 10-for-14 shooting, helping the Zags dominate WSU in the paint by a 42-24 margin. He silenced the raucous crowd three times in the last three minutes by converting two "and-ones" and knocking down a three to give the Zags a 68-64 lead with 33 seconds remaining.
Granted, the seven-foot center's hair during his 31 minutes of action looked like a wet mop being dragged through a fraternity basement the morning after a triple kegger -- but that didn't keep Motum from complimenting the junior from Kamloops, British Columbia. Motum said their rivalry dates back to when the two played for their respective junior national teams.
"It was a good battle," Motum said. "I look forward to more challenges like that. He hit some big shots towards the end."
The politically correct answer from WSU's senior leader did little to deflect attention away from what was an extremely physical battle down low. Elbows were thrown, words were exchanged and the officiating crew hit Motum with a technical foul midway through the first half.
"It was just two guys playing hard," Motum said when asked about the exchange.
Bone said afterward he doesn't mind his all-Pac-12 player getting chippy at times, but noted it's a trait he'll have to manage as WSU winds down their non-conference schedule.
"It's a tough one because I don't want – he's a great kid," Bone said. "But there's great kids and that's what gets them fired up. He's got to manage that. We've talked about it. He'll get better at it."
The Cougars' chances of pulling off a monumental upset looked bleak in the final minute until Motum came through. Trailing 68-64 with 14 seconds remaining, Motum heaved a 30-foot bomb that hit nothing but twine.
GU swingman Gary Bell followed by splitting a pair of free throws before DaVonté Lacy drove the length of the court, laying it in with eight seconds left. That knotted the game at 69 and set up Pangos's remarkable runner with 2.2 seconds left. Lacy then unloaded a desperation trey from three-quarters court, but the attempt fell short.
The sophomore played remarkably in his first game back since suffering a knee injury Nov. 19 against Kansas. He brushed off the typical rust that would accompany missing four games, scoring 22 points on 8-for-15 shooting. He also knocked down four crucial treys to give WSU a chance, three of which came after the Cougars trailed 56-45 with 7:30 remaining.
"For me personally I wasn't shooting real great going into the second half," he said. "My teammates just said keep shooting, keep shooting so I did and it kept falling."
