Salaries for option years in contracts cannot be for a lesser salary than the salary of the previous season. But no such stipulation applies to unguaranteed years. One such example of this is with the recently expired contracts of Steve Blake and Travis Outlaw. Blake's contract paid $4.25 million in its first two seasons, dropping to $4 million in the final one; Outlaw's contract was $4 million for two seasons and then $3.6 mil for the third. By making the final seasons for the duo unguaranteed, even though they had June 30th guarantee dates that made them basically team options, the Blazers were able to use the lower salary trick.
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.
