Kansas freshman Kelly Oubre pumps his fist as he and the Jayhawks take the court prior to tipoff against Washburn on Monday, Nov. 3, 2014 at Allen Fieldhouse.

Kansas University freshman Kelly Oubre Jr., who flushed a fierce one-handed dunk in the second half of Monday’s exhibition rout of Washburn, hustled back on defense without any fist-pumping at all.

That surprised some, considering he recently told the Journal-World’s Tom Keegan he planned on “screaming to the crowd” after some big plays his rookie season.

“I think I better wait,” Oubre said of reacting after such plays. “It was Washburn (Div. II exhibition foe). We had a good game. We were picking it up at that time.

“I didn’t feel I needed to express my feelings,” Oubre added with a smile after scoring nine points and grabbing four rebounds with two assists and two turnovers in his 21-minute debut.

Asked what he thought of his first KU slam, the 6-foot-7, 200-pounder said: “It’s part of the game. I definitely love getting out jumping and dunking. It was definitely one of the highlights of the game for me. It was kind of a momentum shift for us.”

His dunk gave KU a 65-32 lead with 11:40 to play.

His first bucket as a Jayhawk was a three that lifted KU to a 23-7 lead with 9:23 left in the first half.

“I felt pretty comfortable. I don’t like to settle for threes, but I felt the opportunity was there, so I took it,” Oubre said. “We practice a lot in here. We have great feel for the rims. This building is part of us so we feel comfortable in here,” he added of Allen Fieldhouse.

Oubre, who averaged 22.2 points and 6.7 rebounds a game last year at Findlay Prep in Nevada, said he needs to work on “defense, rebounding, doing what I need to do to help my team win. I need to improve on everything.”

He was definitely enthused for Monday’s exhibition opener after practicing against his own teammates for months. He attended both sessions of summer school.

“From the moment we stepped in there, I sensed a thrill like a vibe coming from everybody,” Oubre said of the atmosphere in Allen. “It was definitely one of the best feelings stepping on the court with my teammates for the first time in a real game environment, not just practice. I feel we have a lot of improvement to do. We showed well tonight.”

KU coach Bill Self likes Oubre’s potential, that’s for sure.

“He is so long. He can get out (on defense). He needs to be our best wing defender,” Self said. “We’ve got to be able to plug him in to take advantage of what he does. He can score, but he’s so good around the rim, he’s so good getting out in the passing lanes, he’s such a good offensive rebounder. There’s a lot of things he can do well that’s not your typical two-or-three-guard-type things. So we have to find a way to post him and do some stuff like that that’s a little bit different from what we’ve been doing. But he’s a talented player. He is as good a prospect (as there is) in the gym. He’s got a lot to learn.”

Noted Perry Ellis: “Kelly is relentless defensively. He has some of the best hands I’ve seen, the longest arms. He deflects passes on defense.”

Greene day-to-day: KU sophomore Brannen Greene, who suffered a concussion in Monday’s win over Washburn, did not practice Wednesday. He’s listed day-to-day.

Recruiting: Ivan Rabb, a 6-7 senior forward from O’Dowd High in Oakland, California, who is ranked No. 7 in the recruiting Class of 2015 by Rivals.com, has decided to reschedule this weekend’s official visit to KU, according to Jayhawkslant.com. Rabb has decided to see a game in person this season.
