After guiding a visitor through the basics of Marquette's ball-screen offense on the floor of the Al McGuire Center, coach Buzz Williams was asked if he has found a rotation this season with which he has been comfortable.

"Trying," he said, "trying."

In a yearlong attempt to balance a roster top-heavy with defense, Williams has changed starting lineups, sometimes to begin the second half. He has run players in waves, 11-deep, at opponents, and has sometimes stayed for long stretches with the same group.

It has been a constant experiment to get a little more from an outside-the-bubble team that will take records of 13-10 and 5-5 (Big East) into Seton Hall (13-10, 4-6) Tuesday night.

"I think any rotation by any coach depends on the consistency of the rotation," Williams said. "You could pick a game and go, 'Hey, that should be your rotation.' Then you could look at the next game and go, 'Ah, that's not the rotation.'

"Some of it is matchup dependent. Some of it is dependent upon ... as much as we have struggled to score at times, then we've got to do everything in our power to keep the other team from scoring. Who is it that's helping us offensively, and if they are helping us offensively on a consistent basis, then who is it defensively who is playing to the scouting report and giving us the best chance to win?"

Two recent examples were the home victories against Providence and Butler.

"We're running those dudes in, platooning them," Williams said of the Providence game. "Why? I wasn't picking on anybody. I think we have more on our roster, no better, we have more. We're going to try to play 94 feet."

Butler was altogether a different situation. The Golden Eagles were down by 10 points in the second half, with Davante Gardner and Jamil Wilson sitting.

"We're in foul trouble, so who we start in the second half is going to be different from who we start in the first half," Williams said. "And then you think about the run we went on.

"Our two leading scorers did not play. How can you say for a team that scored 23 points in the first half, the best way to score is to have your two leading scorers in conference play on the bench?"

Todd Mayo got hot, scoring 17 points in the second half, with center Chris Otule, who was weakened by illness, clearing things out for the junior guard.

"It worked out that a-way, so we just rode with it," Williams said. "Todd was playing great. Deonte (Burton) was playing great. Chris completely changed the game. Chris is literally bulldozing guys. I would say of the 27 points Todd and Deonte scored between them, I'd say 10 to 12 were because Chris just bulldozes and opens up the floor.

"Do we have the best offensive players on the floor? On paper, no. Davante and Jamil are our best offensive players. But our highest production in a second half in Big East play came with those two guys on the bench. How can you say that's our rotation?"
