Here are a couple of Celtics-related items that came up in David Aldridge's chat yesterday at ESPN.com. Mark Angelo: Can you please explain what happens when a team buys out a players contract. Does it still count on the salary cap for the length of the contract or does it all count at once?? And why doesnt Boston do it with Baker. Can we say worst trade ever!!!! David Aldridge: (6:28 PM ET ) Depends on what the terms of the buyout are, Angelo. The Blazers opted to give Shawn Kemp his money over a multiple-year period, but he'll only count on their cap for one more year after this one. I think Boston is trying to do that with Baker as we speak, but obviously Baker has other issues to deal with right now.
