That's true -- to an extent. Unless the new CBA either dramatically redefines basketball related income (or the percentage of BRI that will determine the cap) or indexes the cap to some other measure, I'd say its a pretty fair bet that the Spurs know and have accepted that they will be over the cap for the next 6 or so years.
With that, they're willing to pay $64 million for 6 years to Parker, but won't budge on another $2 million -$4 million over the same span. At this point, it's not a matter of staying under the cap or assuring financial flexibility. It's a matter of how much they want to be over the cap -- more accurately, it's a matter of financial austerity. I could certainly see the objection if the additional money would invoke luxury tax payments, but it won't.
Being over the cap is going to tax this team's ability to add big-time talent on a going forward basis. I agree that Parker isn't a superstar player and that $64 million is a more-than-fair offer. But over the course of a 6-year deal, is $66 million really a ridiculous outlay for a team that just got a new building on a promise of increased revenues and a greater ability to spend to ensure the compe iveness of the franchise? I mean this team spent an amount equal to almost half of that $2 million difference on Anthony Carter last season.
