Miami at Dallas 9:00 pm EDT NBA Finals Game One

DALLAS (Ticker) - It has been 35 years since the teams playing for the NBA championship both are making their Finals debuts.

Coaching his third different team in the Finals, Pat Riley begins a quest for his fifth NBA title and first since 1988 when he leads the Miami Heat against the host Dallas Mavericks in Thursday's series opener.

After taking over for Stan Van Gundy on December 12, Riley guided the second-seeded Heat to playoff victories over the Chicago Bulls and New Jersey Nets before eliminating 2004 champion the Detroit Pistons in six games.

Having depended on Hall of Famers Kareem Abdul-Jabbar and Magic Johnson to carry the "Showtime" Los Angeles Lakers to four titles in the 1980s, Riley is hoping for the same kind of production from Shaquille O'Neal and Dwyane Wade.

"When you get this far, .. you can't reinvent the wheel and create a new offense or a new dynamic something to try to beat somebody," Riley said. "You have to go with what it is that you have and what got you here, and hope that you do it at a real high level and take care of all the intangibles, which are the effort areas."

O'Neal, who won three rings with the Lakers from 2000-2002, is averaging 20 points and 9.6 rebounds while shooting 61 percent (144-of-235) from the floor. He scored 28 points to lead Miami in Friday's series clincher over Detroit.

Ranked seventh in playoff scoring average (26.2), Wade led Miami in scoring the first five games against the Pistons. However, he has been bothered by a sinus infection and dehydration.

Despite finishing with the second-best record in the Western Conference, the Mavericks were seeded fourth and swept the Memphis Grizzlies before ousting the defending champion San Antonio Spurs in a seven-game classic.

Sparked by the play of Dirk Nowitzki - the league's fourth-leading postseason scorer (28.4) - Dallas held off the Phoenix Suns in six games to set up the first matchup of first-time finalists since Milwaukee swept Washington in 1971.

"(Coach Avery Johnson) is pushing me to play more of an all-around game, get some points in the paint, post up some more, get some easy shots to the basket, drive a lot more, get to the foul line and just play an all-around offensive game and be in attack mode all the time and not just settle for jump shots," Nowitzki said. "That's what he forced me to do."

The Mavericks have won all 25 games this season when Josh Howard has scored at least 20 points. They also will be looking for the 6-7 swingman to be a defensive force on Wade.

Dallas has won 10 of the last 12 encounters with Miami, including a 112-76 rout here on February 9, which many Heat players feel was their low point of the season.

Game Two is scheduled for Sunday at Dallas.
