Two years ago the three guys who now star on the Miami Heat were doing their own things with different teams. Dwyane Wade was with the Heat, LeBron James in Cleveland and Chris Bosh in Toronto. Then they had a merger which made them come together as one team. Well, not all consolidations are immediately smooth. And when Wade, James and Bosh all joined forces last season, there was no title which left them heart broken. They were amazing players on three different teams (in 2009-10), and they finally came together," said Sacramento coach Keith Smart. They were three individual corporations in one building (last season) because they were good players. They weren't a team yet until they built the chemistry with one another. But they've had a chance to grow to become a better team. . . . They're at a different level now." The Heat sure are armed and ready with the NBA's best record at 25-7 and with an impressive six-game winning streak, Smart says "no question" the Heat are playing their best since the three stars arrived in Miami. Then again, who isn't saying that? With the Heat trying to win a seventh straight game by double digits against Smart's Kings on Tuesday at AmericanAirlines Arena, all the card-carrying members of the Big Three say Miami has not looked this good at any point during the previous 1½ years. "I think that's obvious," Bosh said. "I think we're playing our best ball since we've been together. Things are just clicking." During their six-game streak, the Heat have outscored foes by an average of 17.7 points. They've won 17 of their past 20 since a surprising three-game losing streak in January. "Consistently, yes," James said of the Heat playing the best since he showed up in South Beach. But there is one drawback for James. With games these days hardly ever close, his 36.7-minute average is on pace to be a career low and is more than two minutes below what he logged last season.
