There seems to be a large contingency of folks who think that Antonio McDyess would be a better option for the Celtics than "player X". That may be all well and good, but it's moot.
McDyess isn't leaving Detroit. He left once and came back, he's not leaving again. I've heard this spoken many a time from reputable sources (Marc Spears for one).
So if you don't like "Player X" that's cool, but throw out a name that is a reasonable alternative, because Antonio McDyess isn't walking through that door.
