When the buzzer sounds at the end of regulation, either the Boston Celtics or the Miami Heat will have the 3-2 lead in the series and be one win away from earning a trip to the NBA Finals.

Of course, with the way things have been playing out between these two teams, there could be overtime, proving 48 minutes not enough to decide a winner.

What we do know is that the Celtics are going into Game 5 with all the momentum. Their offense is flowing and with the Heat's inability to organize their half-court offense, the Celtics have looked good defensively as well.

Rajon Rondo has taken the Celtics on his back and made them his team. He leads the team in scoring and, obviously, assists in the series.

The shortest guy on the court is running the show for the Celtics.

The Miami Heat have to toughen up defensively. They have surrendered huge first halves to the Celtics in the past two games, basically digging themselves into a humongous crater.

In Game 3, they were down 13 points at the half and in Game 4, after giving up 61 points, were down by 14.

The Heat will have to help LeBron James, who has played fantastic basketball in the Conference Finals. He has been able to score but when the rest of the offense stalls, James attracts too much attention.

The team's inability to back up James resembles his old days in Cleveland.

Hopefully, for Miami, Erik Spoelstra took some time to create late fourth quarter plays that will work and Dwyane Wade has to return back to his old ways and not miss 15 shots a night.

The Celtics are looking too strong for the Heat. They are playing fearless basketball and are working as a team.

Look for Marquis Daniels and Keyon Dooling to play a vital role in tonight's matchup. They have been tough defenders in the last two games and have created trouble for Miami.

The Heat still need to find a consistent bench scorer as they find themselves with no definite answer on whether Chris Bosh is healthy enough to play.

The Celtics have to keep pounding the ball inside, let Rondo continue improvising and, from time to time, use Ray Allen's resurrected three-point stroke to their advantage.

Game 5 is tonight in Miami. The home team has won all the games in this series.
