The Heat have signed 33-year old point guard Rafer Alston for the rest of this season. He played in 27 games (13 starts) for the Nets this season and he averaged 28.4 minutes, 9.7 points, 2.7 rebounds, 3.9 assists and 1.0 steal per game despite only shooting 34.3% from the floor. He has now played in 646 games in his NBA career (427 starts) and he has averaged 29.0 minutes, 10.3 points, 2.9 rebounds, 4.8 assists and 1.2 steals per game. Alston has always been overrated as a shooter as he has only hit 38.4% of his shots in his NBA career. Look for Alston to bump Carlos Arroyo from the starting line-up soon for the Heat.
