It sure looked like more than one Kansas basketball player had the flu on Saturday at Allen Fieldhouse.

But believe coach Roy Williams when he says only Drew Gooden suffered from the bug during the Jayhawks’ sluggish 87-72 victory over Baylor.

“We brought some medication from the hospital and gave everybody something to try to fight it off,” Williams said, making sure Gooden, who’d had flu-like symptoms since Thursday, didn’t infect his teammates.

“I asked Mark (Cairns, trainer) to check the side effects of the medication to see if it could have made us more sluggish. They said it was not a side effect.”

So the new miracle prescription drug, Tamiflu, which is supposed to squash the flu bug before it stings, couldn’t be blamed for KU’s effort on Saturday.

“I asked Kirk (Hinrich) if he thought that, and he said he didn’t take it  so I told Kirk to go take the daggum stuff,” Williams said after a “workmanlike” effort and “ugly” performance helped the Jayhawks improve to 23-2 overall and 12-0 in the Big 12.

The 6-foot-10 Gooden scored just four points the first half as KU led, 40-36, at the break. He finished with 11 points and 14 rebounds in 29 minutes.

“Everybody could see Drew had been sick. He didn’t have the touch on his jump hook. He struggled more today, yet if a guy gets 14 rebounds, he’s helping the team,” Williams said of Gooden, who the coach hopes will be stronger physically for Monday’s 8:05 p.m. home game against Iowa State. “He was feeling the effects of being sick this week.”

A healthy Hinrich, who has been on fire from the field of late, cooled off with a 4-of-12 shooting performance. He scored 11 points with six assists. He was all over BU’s Wendell Greenleaf defensively, however, holding BU’s second-leading scorer to a 1-for-10 shooting performance, good for two points.

“It was a hard game for us. Kirk has been sensational. He was not sensational today,” Williams said. “He’s a little mad at himself now.

“(But) you go back, if you want to have a great, great year, you will not play at the top of your game every day. You’ve got to be able to sort of meander around and be good enough to win even when you are ugly.”

The Jayhawks won thanks in large part to senior guard Jeff Boschee and junior forward Nick Collison.

Boschee hit four of seven threes and scored 15 points in the first half. He finished with six threes in 10 attempts, good for 21 points. Collison had 22 points on 10-of-15 shooting despite playing just 26 minutes because of early foul trouble.

Boschee said the Jayhawks might have entered complacent after averaging 104.2 points per game the past five games.

“We got fat and happy. We thought we were larger than life stepping on the court,” Boschee said. “We were extremely sluggish the first half and the start of the second half. It was not the best performance we’ve ever had. Effort-wise it was pretty bad.”

The Jayhawks, who didn’t shake the Bears until a 14-5 run opened a 67-56 lead with 7:54 left, didn’t seem to want to punish Baylor for last year’s 85-77 loss in Waco.

“We didn’t play like we wanted revenge,” Boschee said. “We didn’t play up to par. Every once in a while you have to fight through and get wins like that.”

KU won despite hitting 47.1 percent of its shots, 12 of 21 free throws and trailing the Bears in rebounding, 21-15, at the half before rallying late to finally outboard the Bears, 43 to 35.

“Baylor (14-11, 4-8) came out with a plan in mind. They tried to control some tempo, use some time off the clock early in the possession then try to score,” Williams said. “We were out of sync a little bit on the offensive end, to say the least. You have to give Baylor credit, and mentally, whatever it was, we were not into it as much.

“Baylor double-downed in the post and we didn’t do a good job getting it out quickly. We missed a lot of shots inside, missed some layups even dunks. Our post guys were not recognizing the double-team early enough. We were forcing shots, turning it over, making sloppy passes. All of a sudden we got in a groove where we decided to not go inside.

“Drew was shooting a couple of jump shots, Nick shooting a couple of jump shots. The second half we did get it inside more, but still missed a lot of shots.”

Boschee fired up the crowd by hitting a three right before halftime. He’s been big with six threes in each of his last two games.

“Kirk made a great play to find Jeff,” Williams said. “Jeff made a tough shot. In fact Jeff was about our only offense the first half. We were really ugly on the offensive end.”

Williams conceded the fact a letdown was perhaps inevitable at some point.

“This team has been good playing every single day,” Williams said. “Yet human nature  you are not gonna do that. Tiger Woods doesn’t win every tournament, doesn’t birdie every single hole, doesn’t shoot 68 every day. Some days you’ve got to get by playing ugly. And give Baylor credit. They did play well.”
