What the hell is going on here? It is very unusual for players to leave during the season.
I have heard that the new coaching staff has made it very clear to the players that they are not wanted on the team, and are there only to fill things in until the staff can fully recruit a team of their own.
I don't know if that's true, but it explains why so many players are leaving in the middle of the season instead of sticking it out and then transferring over the summer like most player who want to leave do. It also follows along with the coach's statements that he is looking to follow the Al Golden approach to rebuilding - i.e. blowing up the team and starting from complete scratch.
