Also contained within that post was a list of players who had the right to veto any trade. Full no-trade clauses are an incredibly rare occurence; it takes a very specific set of criteria to become eligible for one of those, and for that reason, only two players (Kobe and Dirk Nowitzki) have them. However, players who are signed to one year contracts and who will have either Early or Full Bird Rights when they expire also have the right to veto any trade they are involved in. It's what's colloquially known as the Devean George Rule.
[...] That leaves a market with few shooters on it. And those that are good shooters are either unsuitable or unavailable. Mike Miller's days of being able to defend opposing guards are pretty much over. Kyle Korver can't really do it either. I wouldn't want Quentin Richardson to attempt it. Anthony Morrow is desirable, but is not easy to get. J.J. Redick is also desirable, but he's restricted, and owned by a team who has spent extremely generously in the last two years. Roger Mason is OK, but he's no starter. And then there's Ray Allen, who, while an absolutely perfect fit for Chicago's roster, is setting records for Boston in the NBA Finals. He should be considered unavailable until further notice.
Note: Non-US teams that the player
has played for are, unless stated otherwise, from the top division in
that nation. If a 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
split in Japan.
