Where Ellis is unselfish and Maggette is not is an interesting distinction considering they both pass about equally frequently (not very) ... but Maggette takes FAR fewer shots to get his points and gets to the line a ton. Shots he doesn't take - possessions he doesn't waste are possessions other people can use. Defense is bad - but going to a defense-first culture will help. Also, he is used to being a 6th man - this team has nearly zippo in depth, he would be invaluable. His contract seems bad - but for what he provides (proven, sustainable scoring because of his ridiculous ability to draw fouls) the price is not bad.
Well, unless he's always drawing flagrant fouls, which he isn't, that's not true - you don't need to take a shot to waste a possession.
Maggette's usage rate is 26.1%. In the Celtics, the player with the highest usage rate is Paul Pierce, with a 22.9%.
Of course, Ellis is in Kobe/Wade/Arenas territory with a 29.1 usage rate, but, in all fairness, his assist rate is almost the double of Maggette's.
In any case, I disagree this team has nearly zippo in depth. When healthy, they have a solid 8/9 men rotation. For the playoffs, that's all that matters. I suppose a player like Maggette can help an offensively challenged unit (it needs to be a really bad one), but I fail to see how an unit with 2/3 out of Rondo/Ray/Pierce/Garnett plus Daniels/Wallace comes even close of being offensively challenged.
Plus, is there a player in the league more unpleasant to the eye than Maggette?
