There are concerns at Motown. The Detroit Pistons, the overwhelming favorite to repeat as Eastern Conference champions, are now one game from elimination after the Miami Heat beat the Pistons 89-78 Monday night to take a big lead series 3 to 1. The Pistons had the best record in the NBA (64-18) of the regular season, but lacked focus and seemed lethargic in the playoffs (where they are 9-7). The back wall, the Pistons use the game at a time "mentality when the series resumes Wednesday night in Auburn Hills, Michigan (line WagerWeb. Com game: Pistons -6). "Every game becomes a game of the NCAA tournament,''Detroit coach Flip Saunders said.''We have to understand that back home and our people will have to give us that adrenaline. As I said, things happen. A game can change a game. A game can change a series. Basically, what we have to do is find that playing at home and try to change the series.''What the Pistons must do is stop Dwyane Wade. Dynamic Guard Miami is burning in the Detroit series, especially in the fourth quarter. Wade became the Monday night game to steal the Heat with 12 of his 31 coming in the last 12 minutes. The discouraging news for the Pistons is that they feel they have done everything possible to stop Wade. "We never really in a situation where they were totally in control," Saunders said. "We did a good job of not only provide outdoor Wade, but it's just an incredible list at this time. "The Pistons are on a roll right now. Detroit is averaging over 84. 75 points in a game in Miami 91. 5 and the last two games has reached double-digit loss to Detroit. The main offensive weapons Pistons have not come across this series. Rasheed Wallace, versatile power forward, has seen his average drop score of 11. 5 in a game and has yet to record a block against heat. Chauncey Billups Pistons owner, fifth in league MVP voting, he begins to feel the pressure. "We have a lot of fight in us," Billups said. "We've been down 3-1 before - not against a team as good as the heat, however. And there are very good, man. We have to give. They are. They're playing great ball. Their big men are phenomenal players and others in Chipping quite well. "The heat is coming at the right time. After a regular season of the new additions of mixtures, as Antoine Walker and Gary Payton, Miami has played as a cohesive unit, from submission of Chicago in the first round of the playoffs. Shaquille O'Neal appears rested and refreshed, and contributed 21 points and nine rebounds Monday night. And then there's Wade, who has stepped up his game in Jordan-like level of this series, averaging 30. 8 points. "There is no doubt that the end of the season and the playoffs, he became a better basketball team," said Miami coach Pat Riley. "This is really the unit. "Riley has never lost a series when ahead 3-1 and 11-0 in those situations. In addition, each of the last 16 teams advance to 3-1 in the conference finals has passed the first round of the championship. "It's 12 wins, and that's it," Riley said. "I really think we're hungry, and I think we'll get him. We have great respect for the Pistons, but I think our heart without her. "
