The Blazers are in kind of a tight spot with respect to re-signing Joel after next year. Using StoryTeller's numbers, the Blazers are currently committed to the following contracts for the 2006-07 season:
Theo Ratliff: $10,894,737
Derek Anderson: $9,742,500
Darius Miles: $7,619,048
Ruben Patterson: $6,807,000
Zach Randolph: $12,000,000
Sebastian Telfair: $1,793,160
Victor Khyrapa: $1,172,400
Travis Outlaw $1,836,426
Total: $51,865,271
That doesn't include another $1,000,000 or so for Segei Monya, 2-3 mil for our first round pick from this season, any contract extensions they may give Ha Sueng-jin and Richie Frahm, plus whatever they may do in the way of free agent signings this summer. While we don't know exactly what the salary cap will be under the new CBA, as things stand, it looks like the Blazers will not be in a position to offer Przybilla anything more than a mid-level exception deal. If Joel wants to cooperate, the Blazers could give him a MLE deal with a one-year player option. At that point, after his 3rd season as a Blazer, they could give him a max deal using the Larry Bird exception. If there are teams out there in the summer of 2006 that need a center and have cap space, it's entirely possible that the Blazers could lose Joel the same way Indiana lost Brad Miller.
One possibility that I would think that the Blazers would be considering would be to try to work a trade of one or more of our committed contracts for a player with an ending deal. Something like DA plus Miles or Patterson for Antonio Davis and change would fill the bill. Even at that, though, they wouldn't have much in the way of cap space. Those contracts to Theo and Zach are looking really bad at the moment. Failing to give Joel a 3-year contract rather than a 2-year deal is also looking, in hindsight, to be a really poor move.
Maybe Joel will cooperate with the Blazers on the MLE idea or perhaps the Blazers will be able to find two ending contract deals to make to clear more cap space.
