Last time he played Kansas University, David Harrison displayed his frustration through tears.

Sunday, the Colorado big man was ready to tussle with KU faithful in Allen Fieldhouse.

“You’re just a big baby. Go to the locker room,” said one Kansas fan, whose taunt after Harrison fouled out with 10:33 left in Kansas’ 78-57 victory Sunday started a shortly-lived standoff between Harrison and a group of Jayhawk supporters in the south student section.

While none of the students were able to hear the 7-foot, 270-pounder’s rebuttal over the crowd’s boos, they certainly realized Harrison’s anger when he started walking toward them. He had to be restrained by Colorado personnel.

“Sometimes it is frustrating for David, and we all asked him to take it and suck it up,” said Colorado coach Ricardo Patton, who had ordered Harrison to watch the rest of the game from CU’s locker room moments before his oral skirmish.

After the game, Harrison was not allowed to talk to the media and was ushered to the team bus.

“It is not easy for a young man to do that all the time when you feel like you’re treated different,” Patton said.

There’s no doubt Harrison feels he’s treated different every time he takes on the Jayhawks. Since his freshman season, when Harrison and his brother, D.J., got into a squabble with former KU All-American Drew Gooden, there has been no love lost between Kansas fans and the Harrison brothers.

“I don’t know what it is. They’re on him all the time, right when he walks in,” said Buffaloes senior guard Blair Wilson, who scored just three points, nine points below his average. “I don’t know if he said some stuff a couple of years ago or whatever it was.

Kansas University's Jeff Graves, left, scores two of his six points despite the defense of Colorado's David Harrison.

“It’s just tough. We were all frustrated, and that just added to it. When you’re getting blown out, it’s easy to lose your head.”

Harrison has made a few controversial remarks about KU in the past.

He said Oklahoma’s 2001-02 team was better than the Jayhawks’ that season, even though KU went undefeated in the Big 12 Conference to win the league crown.

And Harrison said, “Kansas is gonna get theirs,” after a 97-85 KU win in Boulder, Colo., in his first game against the Jayhawks.

He seemed to be under control early in Sunday’s game.

After KU’s 6-0 start, a Harrison dunk with 17:11 to go in the first half capped a 7-0 spurt by CU.

The Buffaloes (10-6, 2-3 Big 12) regained the lead once more, but a technical foul against Patton at 13:08 signaled the end for Colorado.

Kansas used the infraction to start a 5-0 run, before CU’s Lamar Harris, who scored a career-high 21 points, answered with a jumper.

That basket would be Colorado’s last for more than 10 minutes, and the Buffs shot only 17.9 percent in the first half. Meanwhile, Kansas went on a 22-7 run during that time and built a 20-point halftime lead, 41-21.

Frustration clearly set in the second half for a Colorado team that has won just one road game in 37 attempts since 1990-91 against nationally-ranked opponents.

Harrison — who, after CU’s 77-62 loss to KU Jan. 5 in Boulder, shouldered the blame and broke down crying — picked up his third and fourth fouls within 14 seconds at the 17:02 mark.

Harrison, who was averaging 16.4 points per game and 8.6 rebounds, had his lowest productivity in six games against the Jayhawks. He scored just five points and grabbed only two rebounds in 14 minutes.

“He gets fouled a lot, but he doesn’t get all the calls he would like to get,” CU guard Michel Morandais said of some questionable fouls that went against Harrison late.

“He’s a competitor. In a way he’s a fighter, so he goes out there and does the best he can,” said Morandais, who made only three of 15 shots. “When the calls don’t go your way, though, it can get frustrating at times.”

Still, Patton said his center once again struggled with immaturity.

“This is a difficult series for David because he hasn’t really figured out how to handle all the taunting from the fans,” said Patton, whose teams are 1-19 all-time against the Jayhawks.
