Beating the Heat is something no NBA team has accomplished since Feb. 1, when the Indiana Pacers posted a 102-89 victory over Miami in Indianapolis. Since then 20 opponents have tried and failed to stop the Miami machine led by LeBron James, Dwyane Wade and Chris Bosh. The Milwaukee Bucks will take their chance at 7:30 p.m. Friday night at the BMO Harris Bradley Center. And it will take a concerted effort if the Bucks want to snap the streak, which the Heat extended to 20 games with a grind-it-out 98-94 victory in Philadelphia on Wednesday night. "I have no idea of what it is to win 20 games in a row," Bucks coach Jim Boylan said. But the Heat is going for more, trying to tie the 2007-'08 Houston Rockets team that won 22 straight games. The all-time league record of 33 games set by the 1971-'72 Los Angeles Lakers - which, incidentally, the Bucks ended with a 120-104 victory at the Arena - is still in the distance. The Bucks had a 20-game streak of their own during the franchise's championship season in 1970-'71, when Kareem Abdul-Jabbar and Oscar Robertson were dominant. But to show the measure of the Heat's accomplishment, no Bucks team has won 10 games in a row since the 1985-'86 season under coach Don Nelson. "They won the championship last year, and with a championship comes a certain amount of confidence," Boylan said of the Heat. "They're sure of themselves and accepting their roles from top to bottom." For instance, veteran and former Bucks star Ray Allen is coming off the bench for the first time in his career to play an important role for the Heat. James and Wade are leading the way with sensational play. It was symbolized late in Wednesday's game when James missed two easy shots at the rim, but Wade followed with a key tip-in to keep the streak alive.
