The Celtics are looking at Antonio McDyess. If he signs here Billy will most likely be headed to the D league.
They're going to replace a 2/3 with a 4/5? They seem like two very different players.
They wouldn't be replacing Bill they would be replacing the roster spot. It would be either Bill, JR, or Cassell, it could potentially be Patrick O'Bryant as well but he has been getting some tic. They won't release Cassell and it seems unlikely that they would send down their first round draft pick. They are loaded at the 2/3 positions, they have 6 different guys that can play those positions while they only have 3 big men.
They have to wait 30 days to sign McDyess so it is nothing pressing, but as it looks now he may be the victim of a numbers game if it goes down.
