well, to be honest, i don't really understand why pulling the chair shouldn't be considered illegal. There are so many minor fouls being called in basketball today that I don’t see why this one— which is actually dangerous— shouldn’t be, especially when the move is as obvious and intentional as holliday's one.
that's absolutely true that often, Wemby's drives to the basket are not really under control but still, i find it as dangerous to pull the chair, even if more rare, than going too close to the landing spot of a shooter.
after all, illegally causing an opponent to lose balance and fall over is a foul. that's true that in the case of pulling the chair, there isn't necessarily a contact but still, it's the same kind of foul. it's kinda a bitch move....
