I don't think it's necessary. I'm on the owners side, but if I'm the players I'd say "Hey look, we'll take the deal you have tabled contingent on the sole idea that you do not decrease our % share of revenue, ask for a salary rollback, redefine HRR, or in any other way, shape, or form, pitch us a CBA that reduces the percentage of money the PA is entitled to.
You don't think it's necessary? In the middle of a lockout? The quaint little 'maybe we get a season' options are OVER. It's time to go all-out to make sure a season happens by any means necessary, and that a work stoppage never happens again, it's unacceptable.
