Worthless player.
One of the worst contracts in the NBA.
These are two completely different concepts.
Perk was top-20 in overall defense this year. That's not worthless.
Yeah, but it does put him in the tier of players along the lines of Reggie Evans or Matt Barnes (well the Matt Barnes of every year other than this one).
Limited role player who has one elite nba skill and is doing everything else poorly.
Makes me sad.
Yeah, Perk has declined. People forget how good of a player he was in 2010. 10 points, 8 boards, 2 blocks, 60% shooting. Only ten players in the history of the league* have had a stat line where they put up stats at least as good as Perk in those four categories.
Even in decline, though, I think there's a lot of value for a guy who anchors your defense and who allows Ibaka more flexibility to defend on the perimeter. That's not $9 million in value, but it's got definite value.
(* Or, at least since blocks were counted as a stat beginning in the early 70s.)
