@ParisHawk Good question.
ESPN recap, discussing stars for KU, started with Cole: "Aldrich stood out, swatting three shots in the first half and altering more after coming off the bench en route to his eight-point, seven-rebound night. His highlight came after KU missed just its fifth shot of the game, more than 10 minutes into the first half, and he outgrappled Hansbrough for a rebound that resulted in two free throws. That made it 33-10."
Watching a Youtube replay of the first half, Aldrich entered the game with 14:34 left in the 1st half when Kaun got his second foul with the score 13-6. The lead got up to 38-12 at 7:30, when Billy Packer p.o.ed the suits by declaring the game over. Got up to 40-12 at 6:38 before UNC started their comeback at 4:40. The half ended at 44-27.
Before that game, in the 4 prior tourney games, he had a total of 6 fouls, 4 pts, 4 rebs, 1 block, and 0 FTs in 20 total mins.
For the game against UNC, Aldrich, in 16 mins, had 8 pts (4-4 FTs), 7 rebounds, 1 steal, and 4 blocks with 1 pf. Almost all of that was in the first half. (Hansbrough, in 36 mins, had 17 pts, 9 rebs, 0 blocks, and 2 steals.)
The praise for Aldrich isn't that he played so stupendously or that he single-handedly defeated UNC. It is that he came off the bench in a crucial situation as a freshman in the biggest test of his life until then, played the POY of the year evenly, and gave the rest of KU's players the room to move on offense and take risks on defense by giving KU much-needed rim protection.
He played like a veteran, helping KU totally dispel the notion of UNC being invulnerable. What other relatively unused bench frosh has done that in a Final Four?
