Read my full game story on Minnesota's 62-58 win over Purdue at home here.
DeAndre Mathieu had just missed the front end of a 1-and-1 and the raucous crowd and gaggle of beat reporters trying to save their running stories probably all had the same thought:
Oh boy, here we go again.
There were 23 seconds left on the clock -- plenty of time for a hot-shooting Purdue to make a play.
The Boilermakers worked the ball into the paint, where forward Vince Edwards got it. The 6-foot-7 freshman started to go up with it when Walker's hand appeared to rake over the top. The ball tipped out of Edwards' hands and Andre Hollins wound up with the defensive rebound.
Then everyone sort of just froze. The crowd slouched. Everyone seemed to be waiting for something for about two seconds. Minnesota players later said they thought they heard a whistle.
"I don't know what it was," Hollins said. "But I looked at the ref and then I looked at everybody else and the ball was coming toward me so I just grabbed it."
No whistle had been called. Walker was credited with a block, Edwards' heave was ruled a missed layup and Purdue was forced to quickly foul Hollins, who nailed a pair of free throws with four seconds left and iced the Gophers (15-9; 4-7) 62-58 victory.
