Three games into his first season with the Heat, reserve guard Ray Allen is making 56.3 percent of his three-pointers, which is third in the NBA among players with at least 10 attempts.

Yes, the Heat has its Big 3, but it also has the guy who makes big threes, and that's Allen.

The Heat, which hosts the Phoenix Suns at 7:30 p.m. Monday, rested Sunday, which will be a major advantage against the Suns, who played at Orlando on Sunday.

The Suns will arrive in Miami on Monday for Part 2 of back-to-back road games. Even more tiring for the Suns is the prospect of chasing around screens to keep up with the 37-year-old Allen, the most prolific three-point shooter in NBA history.

Allen so far appears to have been an astute free agent signing for the Heat. In fact, it's conceivable the Heat could be 0-3 right now without Allen, who hit the game-winning shot Saturday in a 119-116 victory over Denver. He also had 19 points in a 13-point win over Boston on opening night.

Allen is fourth on the team in scoring average (15.7), trailing only the Big 3 of Chris Bosh (23.7), LeBron James (23.0) and Dwyane Wade (19.3).

With all that firepower, it's no surprise the Heat ranks first in the NBA in team scoring average (107.7).
