Boulder, Colo. ? He dribbled wildly into an offensive foul. He took another wild shot that was blocked and even fired up an airball. Mario Chalmers looked like a freshman at times in his first Big 12 Conference game.

But, man, when he didn’t show his youth he sure showed his talent in supremely entertaining fashion Wednesday night at Coors Events Center, where Kansas University ran to a 75-63 victory over a veteran Colorado team.

The Jayhawks couldn’t shoot straight from the outside for most of the night, but the way they ran their way to easy buckets when Chalmers and Brandon Rush were on the floor together, it didn’t matter.

With KU’s lead at five points and 10 minutes remaining in the game, here’s what Chalmers did on the next four offensive possessions:

¢ Pulled up for a 12-foot baseline jumper and hit it.

¢ While running the break, showcased his inventive passing ability by faking everyone in the building into thinking he was going left and hit Rush on the right side for a layup.

¢ Again running the break, tossed up a beauty of a lob for C.J. Giles, who had blocked a shot to start the break.

¢ Hit a three-pointer from the left wing.

Just like that, in a span of 91 seconds, Chalmers had stretched the lead to 11 points, and it never got closer than seven after that.

The Jayhawks desperately needed better guard play in the second half because the six perimeter players used in the first half combined to make one of 15 shots. Rush (all 17 points in the second half) and Chalmers combined for 26 second-half points. For the night, Chalmers had 11 points, six assists, three steals and three rebounds in 17 minutes.

It’s the 91 seconds he’ll remember the longest. He agreed it was his best stretch as a college player.

“The baseline shot I felt comfortable taking,” Chalmers said. “He backed off, and I put it up and it went in. The pass came on a three-on-one. I just tried to make the defender cover me and got Brandon an easy shot. The three pointer : my teammates found me from my pick, and I was able to finally knock one down. I have to give credit to my teammates for looking for me and having confidence in me.”

After making one of two three-pointers, Chalmers improved his long-range success rate to 24 percent. As a senior at Anchorage Bartlett High, Chalmers led Alaska in three-point shooting.

What’s happened to his touch?

“I don’t know,” Chalmers said. “It’s just not falling.”

In time it will, and defenders will have to guard him more tightly. He’ll blow by them and find even more opportunities for teammates.

For now, he’s helping his pals get so many layups on the fly that even without hitting threes, he’s a valuable player.

“We’re getting better by the moment in transition,” Chalmers said. “At practice every day, coach preaches to us run, run, run, and that’s why when we get into a game it feels just like practice.”

In practice, there is no enemy student section, a first for Chalmers.

“Hearing the crowd saying stuff about you to try to get you out of your game was new to me,” Chalmers said.

It didn’t work.
