<div class='quotetop'>QUOTE </div><div class='quotemain'>MIAMI — The bedrock of the Heat - All-Star Dwyane Wade and team captain Udonis Haslem - conceded for the first time after Wednesday's 96-85 loss in Philadelphia that the team's foundation is cracked. Wade said some players still don't know the defensive schemes, even though Miami (8-21) is more than one-third of the way into the season. "A lot of teams score on the scheme, on maybe certain guys not knowing where to be or what to do," Wade said. Of the 13 players available to coach Pat Riley, seven are in their first year with the Heat. Wade, in his fifth season with Miami, said that on past teams "we always knew the principles of what we do," even when the defense wasn't playing well. Wade said the same lack of knowledge haunts the offense. "Guys don't understand how to get their shots, when to get their shots, and the time to do it," he said. "It's a lot of internal things in individuals that's the cause of us not playing as well as we need to." At least it appears that injuries won't be a big factor in the immediate future. Point guard Jason Williams had an MRI on his left knee and it found no damage. He's a game-time decision for tonight's home game against Orlando (19-11). Center Shaquille O'Neal had his left hip checked out by a doctor and is expected to start tonight. Reserve guard Chris Quinn is out of the walking boot for his sprained left ankle but remains questionable. Even when the team is healthy, it is suffering from a lack of cohesiveness compared to past Heat squads, said Haslem, who also is in his fifth season. "The difference between those teams and this one, I guess, is we knew a little bit more about each other. We knew our games a little better," he said. Frequently this season, Heat players have openly bickered after opponents' baskets, yelling at each other and pointing to spots on the floor. Haslem said most of that is everyday life in the NBA. "Maybe we're just showing a little too much frustration about it," he said. "Instead of going out and playing, (maybe) we're letting it bother us." For a team that hasn't seemed to worry about regular-season stumbles the past four years, these were relatively stunning admissions. "It's tough to lose, period," Wade said, "but it's tough to be the worst team in the Eastern Conference and don't know from one night to the next what you're going to see." Even O'Neal, who never seems to worry during the regular season, said that "there is not panic, but concern" about the Heat being 13 games under .500.</div> Source: Palm Beach Post
