How does it screw SA?
If they're under the cap less than the MLE they can still use it.
Funny, while the Spurs organization and Spurs fans were disappointed with Jefferson's underwhelming play last season, his opting out of the final, inflated year of his contract still leaves the team worse off.
As I understand it, San Antonio had earmarked most or all of the MLE for Tiago Splitter, meaning that short of resigning Jefferson to a longer deal the team will have to try to find a starting SF for the bi-annual exception...
The Spurs don't even have another true 3 on the roster.
