"It's the most important game because it's our next game," James said flatly. "That's how we approach this game and we look forward to the challenge."
Added Bosh, "Before we got too much ahead of ourselves. That was a problem. We have to keep playing, keep working the game, and not really think about sweeping people."
Make no mistake, though, the Heat would like to cross a sweep of their "to-do" list. (If nothing else, they'd have at least five full days off before the Eastern Conference semifinals would start.)
"That was our concentration and emphasis today: It's 24 hours to do what we have to do," Spoelstra said. "That's why we don't want to short cut any of the preparation. It's their last stand, we know what that can be like. The last two years, we've lost a game in this situation. Hopefully we can learn from that and find a way to close it out."
Milwaukee, meanwhile, would love nothing more than to extend its season by at least two more days. Game 5 would be Tuesday in Miami.
This is still a relatively young Bucks team with Larry Sanders in only his third season, Brandon Jennings his fourth and Ersan Ilyasova and Luc Mbah a Moute their fifth. It's Milwaukee's first playoff appearance in three years, and the experience, regardless of how long it lasts, will be invaluable.
"Everybody's getting something out of it," coach Jim Boylan said. "We're in the middle of it, but there's time you reflect, you look back, you watch the games and see certain things that happened and you can adjust and make a difference for your team. I'm sure that, at the end of this series — whenever this series is over — all our guys are going to look back and take something positive from it."
But they hope that won't be for a few more days.
"(Sunday) is going to be our fourth game and it could be our last game," Sanders said. "But hopefully guys don't want it to be our last game."
Notes: Bosh sat out some of Miami's full-court work with sore legs, but Spoelstra said everyone but Wade is "ready to go" for Game 4. ... The Bucks have no health issues, Boylan said. ... Sunday's game on ABC is a rare appearance on broadcast television for the Bucks. "With my rabbit ears on my TV, I can get this thing," Boylan cracked.
