Purdue got one final look with fewer than 10 seconds remaining, but the shot bounced off the rim and was chased down by Admiral Schofield. James Daniell III then went to the foul line and made two free throws to seal the victory.

Coaches talk following the game

Following their first 3-0 start since the 2010-11 season, Tennessee coach Rick Barnes was proud of how his team fought back: "I thought we really showed the toughness we've been looking for from them," he said."I thought our guys just kept finding ways to fight back."

Purdue coach Matt Painter felt his team gave the game away: "We have a skilled team, but we've got to win the possession wars. We've got to outrebound our opponent. We have to have fewer turnovers. When you do, now that skill is really going to help you. I thought tonight we gave Tennessee a lot of help."
