I actually don't mind Joel Anthony too much. He's a liability on offense, but he's a good shot blocker and decent post defender. He's a bit small but works pretty hard, or so it seems. Not to mention he still has room for improvement.
Jamaal Magloire, on the other hand, is a liablity on offense and a below average defender. Magloire has no more room for improvement, whatsoever. He is washed up and very well out of his prime.
The Heat haven't made a big move yet, but these little moves could be the difference between getting home court advantage in the first round of playoffs and not.
