Maybe he was going to the Cs locker room to ask Pierce how a SF is supposed to lead a team with good players on it? Melo certainly still has no clue what it takes to be a true leader in the NBA.
I'm pretty sure at least a half dozen Boston players could beat up Melo - Sully, Bass, Collins, KG, Pierce, and Rondo (good hand and foot speed).
If Melo was even outside the Cs locker room causing a scene, He'd got to be suspended at least one game. DMC got a two game suspension for yelling at a TV analyst.
