It's the loneliest job out there and a thankless one at that, trying to slow down Miami Heat star LeBron James.

That's the nearly impossible task given to Bucks forward Luc Richard Mbah a Moute in Milwaukee's playoff series against the top-seeded and defending league champion Heat.

But hold on a minute.

Even after James nearly posted a triple-double and went 9 for 11 while scoring 27 points, grabbing 10 rebounds and handing out eight assists in Game 1 on Sunday, Mbah a Moute said it could be done.

"No, it's not impossible," he said at the Bucks practice session Monday at American Airlines Arena. "He did a good job of using screens.

"He scored in a variety of ways, getting out in transition. We have to make an adjustment on how to guard him on the pick-and-roll.

"It's one thing to guard him but it's another thing to guard him when there's a pick-and-roll. Every time we were aggressive on the pick-and-roll, it helped.

"And I've got to do a better job of staying into his body and being more aggressive."

Sometimes the Bucks will send a second defender at James to try to force a turnover or a mistake.

But even then, James knows exactly where his teammates are on the floor and is adept at finding them.

James and the Heat pulled away in the second half to grab a 110-87 victory in the opener of the best-of-seven Eastern Conference series. Game 2 is at 6:30 p.m. Tuesday before the series switches to Milwaukee for Game 3 on Thursday night.

Mbah a Moute has defended the elite players in the league since his rookie year after the former UCLA forward was chosen by the Bucks in the second round of the 2008 draft.

He has taken his turn on Kobe Bryant, Kevin Durant, Chris Paul and Derrick Rose, defending everyone from bulky power forwards to lightning-quick point guards.
