There was a buzz inside the Coors Events Center on Thursday night.

The sellout crowd of 11,212 sensed it was witnessing something special during Colorado's rousing 75-54 romp over Stanford.

They were right.

Andre Roberson's memorable and menacing defensive performance included the collection of 20 rebounds, matching his career high set at Fresno State on Dec. 12.

Entering Friday's games, CU's elastic 6-7 junior forward was officially the nation's most productive glass cleaner, averaging 11.9 rebounds per game.

Siena's O.D. Anosike (11.6 rpg) was second. Roberson is averaging nearly one more board per game than the Pac-12's second-best rebounder, Oregon State's Eric Moreland (10.8 rpg).

Just imagine if Roberson boxed out?

CU head coach Tad Boyle says his star pupil is the exception to the rule when it comes to rebounding.

"It's kind of one of those coaching clinic conversations that you have: Would you rather have a guy who can box out every time, or a guy who never boxes out but can go and get the rebound?" Boyle said with a smile after Friday's practice. "He's the first guy I've coached where I say, 'OK, don't box out. Go and get the rebound.'"

After the inspired performance against the Cardinal -- Roberson also had 12 points, three blocks, three steals and two assists -- he said the only statistic that mattered was the result on the scoreboard.


"I don't really look at numbers after the game. What really matters to me and the team is the win," Roberson said. "When we were on a slump, I told our team we were going to be on the rise again, and I think you've seen that these past couple of nights. We started to play together as a team and we kept fighting. Hopefully we can keep it going."

The Buffs (13-6, 3-4) have the same overall record as last year's team did at this point.

Aside from the obvious focus of getting CU back to the NCAA Tournament, Roberson admits that leading the country in rebounding is in the back of his beautiful basketball mind.

"That was definitely one of my personal goals from the beginning," Roberson said. "I just have to keep doing what I do for this team. Right now, I feel that's defense and rebounding, preaching what coach Boyle does."

It was definitely a team effort against Stanford.

Askia Booker scored 13 points on 6-for-9 shooting and has pitched in with 11 rebounds during CU's current two-game win streak.

Josh Scott (12 points, five rebounds) and Xavier Johnson (11 points, three rebounds) helped Roberson flip the script.

Last year the Cardinal swept CU by scores of 84-64 and 74-50 while dominating the glass 85-53.

The Buffs' 21-point victory Thursday had a lot to do with a 48-30 rebounding advantage.

"I give credit to our big guys. Coach made us hit the weight room really hard these past couple of days," Booker said. "Xavier Johnson started (Thursday) and made a big impact. Josh Scott was making some great post plays.

"I can't even really speak on Andre Roberson. I mean, 20 rebounds is ridiculous."

Roberson led the Pac-12 and was ranked third nationally in rebounding last season (11.1 rpg) while breaking Burdette Haldorson's 58-year old CU record for rebounds in a season (401).

Haldorson (4), Jim Davis (3), Cliff Meely (2), Jamahl Mosley (2) and Roberson (2) are the only Buffs to grab 20 or more rebounds multiple times.

"Each year he gets a little bit smarter, a little more experienced, a little craftier," Boyle said of Roberson, his first recruit at CU. "What makes him a great rebounder, I wish I could coach it, I'd have about 10 of them. It's pretty special."

Roberson led CU in rebounding, steals and blocks as a freshman and sophomore. He's on track to do it again averaging a Buff-best 2.1 steals and 1.5 blocks so far this season.

During the Buffs' 59-58 win at Washington State last Saturday, Roberson joined Stephane Pelle (1,054), Meely (971) and Shaun Vandiver (962) as the only players in program history with at least 900 career rebounds.

Entering Sundays' home game against Cal, Roberson has 925 career rebounds.

"When a young man gets 20 rebounds in a 40-minute game, that takes effort and a lot of energy," Stanford coach Johnny Dawkins said. "It says a lot about that kid."
