Fatigue May Be a Foe for Duke INDIANAPOLIS - Before anyone could ask a question at the news conference after Duke's win over Michigan State, Blue Devils Coach Mike Krzyzewski made a request. "Ask them quick," Krzyzewski said. We've got a game tomorrow. Literally. It was after 12:30 a.m. Saturday, and time was already getting short for Duke to begin preparing to face top-seeded Louisville in the Midwest Region final Sunday evening in the N.C.A.A. tournament. After a slugfest with the Spartans, Duke might have another opponent besides the Cardinals: fatigue. The Blue Devils were the first team to the news conference podium Saturday at 12:50 p.m., and the players shuffled into the room looking visibly worn down. The team did not return to the hotel until close to 1:45 a.m., and after a big win, they admitted it was hard to relax and sleep. "You still have to let your adrenaline calm down," guard Rasheed Sulaimon said. It was a long night for a lot of us. The wakeup Saturday was 10:30 a.m., and the team immediately began looking at film of Louisville and talking about strategy, going down a long checklist of objectives and priorities the Duke coaching staff already scrambled to assemble. In the locker room, a projector screen and chairs were set up to watch more tape the rest of the afternoon. "We're concerned about our turnaround from last night more so than their press," Krzyzewski said. We have to do make sure our guys enter the game with fresh legs. The Duke players insisted they would be fine, with Sunday's 5:05 p.m. Eastern tipoff giving them enough time to rest. "They'll probably have us go to sleep a little earlier tonight, but we'll be fine," forward Josh Hairston said. It was a long, mostly sleepless night for the Duke coaching staff, which Krzyzewski hinted at the night before, when he looked at his watch and shook his head. He said preparation for the Cardinals would have to come "in stages," meaning that the staff could not put together a game plan for Louisville all at once. "We would've been up all night no matter what," Krzyzewski said Saturday, referring to the sleeplessness his staff would have had if the Blue Devils would have lost to Michigan State. It's better to be up all night this way. Louisville, on the other hand, after playing the earlier game Friday, appeared to be much sharper. Working against the Cardinals is an illness that has made the rounds of the locker room since earlier this week. The players said their immune systems are improving. "I think the game last night helped us," guard Peyton Siva said. Oregon running so much ran it out of all of us.
