(Note: Speaking of Boston, and their equally transparent attempt to land Troy Murphy once he's been bought out by Golden State, there is no date by which free agents must be signed to be eligible for the playoffs. This is proven by the historical cases of players such as Lawrence Funderburke with Chicago in 2005, Derrick Zimmerman and John Thomas in 2006, and the oft-mentioned Anthony Carter with Denver in 2007. There is only a waive-by date. Players on an NBA roster on March 1st can only play in the playoffs with the team whose roster they are on. If they're a free agent on that date, or signed with a non-NBA team? They're eligible for anyone. Go nuts.)
Note: Non-US teams that the player
has played for are, unless stated otherwise, from the top division in
that nation. If league or division name is expressly stated, it's not
the top division. The only exceptions to this are the rare occasions where
no one league is said to be above the other, such as with the JBL/BJ League
In the event where more than one agent is listed, this is because the
player has more than one agent. This is rather commonplace - a lot of
times, a player will sign with a big agency, and they will have both primary
and secondary agents from within that agency to handle their affairs.
(Where that happens, the primary agent is listed first.) Also, foreign
players tend to have both American and domestic agents. Where the details
of such are known, they are listed.
