How was the Wisconsin coach to blame? He called a timeout because Michigan was in a full court press when the game was decided. Michigan still had their starters in the game, Wisconsin had their reserves in the game. Michigan presses slaps the ball out of bounds with 4 seconds to get over the line. The Wisconsin coach called timeout to reset the 10 second clock. Juwan is 100% to blame; you can't blame the Wisconsin coach for calling timeout if you're still pressing. If you stop pressing the point guard dribbles the ball until time expires.
If you're still in the full court press at that point of the game, you put your big boys on, shut up and walk off the court. Cause its all on you.
