Colorful, controversial Colorado center David Harrison isn’t guaranteeing a victory against Kansas University in Sunday’s Big 12 Conference clash at Allen Fieldhouse.

But the Buffs’ 7-footer, who in the past has infuriated KU fans with his comments, isn’t discounting the possibility of a Buffs’ win, either.

Tipoff is 1 p.m. at Allen Fieldhouse.

“It’s doable,” Harrison told the Colorado media after CU’s 71-62 loss Wednesday to Oklahoma State. “I’m not saying they are a pushover or anything like that. But it’s doable.”

The Buffs (10-5 overall 2-2 Big 12) have dropped 20 straight games at Allen Fieldhouse, last winning there Feb. 10, 1983.

And yes, Harrison expects to be booed.

“I don’t care,” he said. “They can say what they want. Getting heckled on the road is a sign of respect.”

Harrison, who is 1-5 against KU, and his teammates have been off-limits to the media since the OSU game. CU coach Ricardo Patton has banned player interviews before the CU-KU game in Lawrence the past two season.

It could be to prevent quotes like Harrison’s “KU will get theirs” prior to the teams’ 2002 meeting in Lawrence.

He also said Oklahoma, not KU, had the best team in the league entering the 2002 Big 12 Tournament, despite the fact KU won the league title. In response, KU’s Drew Gooden refused to shake Harrison’s hand during warmups at Kemper Arena in Kansas City, Mo.

Also in 2002, the Nashville, Tenn., native said KU coach Roy Williams had sent him a letter during his senior year in high school, asking him to attend either Vanderbilt or North Carolina, not Colorado. Williams said he was “99 percent sure” he never sent that letter.

For his part, Harrison was gracious his freshman year after a middle-aged KU fan screamed at him outside the visitor’s locker room. Harrison approached the fan to shake his hand, defusing a potentially dangerous situation.

As far as this year’s “doable” comment, it was made prior to KU’s 69-68 loss Thursday to Richmond, a game that might make teams believe they can win in Allen.

“I’m sure anybody comes in here after seeing last night’s game would say, ‘Hey, if we play well we have a chance,'” KU coach Bill Self said Friday. “I’d certainly tell my team the same thing.”
