Rasheed Wallace - his tantrums overshadow his talent.. Yes he creates fanfare, but it's not his skills in basketball that's being talked about.. I'm not Piston fan but I agree with coaches who acknowledge the impact he brings into the game. He can score under 20 points and just grab 6 rebounds and still change the game. And just when he's about to up his credentials as a superstar, he begins to eat the referees with his eyes. A typical Rasheed Wallace feature on Sports Center would be: a video clip of a Pistons game. The commentator saying "Wallace with a turnaround shot", as footage rolls, "'Sheed in the zone", another footage rolls, "Rasheed Wallace commits a foul", then a footage of Wallace complaining to the refs... And sometimes, the footage shows him chasing referees. That's why he's underrated.
*Don't forget that he was the final piece of the puzzle when they beat my Lakers in 2004 Finals.
