Where would the Celtics be if they had signed McDyess instead of Sheed?
Not sure; I don't think McDyess has been that great for them, either.
Agreed. So far both additions have played out as a zero-sum game.
True. But as Hubie pointed out earlier in the quarter when Sheed posted up Bonner, when Sheed is in the post, he can command a double team? How many teams have a backup 4/5 you can say that about? There's some teams in the league who don't have a starting 4/5 you can say that about.
Granted, he hasn't played all that well during the regular season. However, in both the case of Sheed and Dice, neither the Celtics nor the Spurs got each player for the regular season.
