Why should the players budge? Bettmans proposal is take, take, take, take, take, take, take and take. Not a single proposal to sweeten the pot, no "we want to take this, but we'll give you that in return" to make them go "OK". Bettmans proposal isn't a negotiation, its an ultimatum. He's treating the NHLPA like a vanquished foe trying to get the least punitive terms out of an unconditional surrender, rather than an equal partner in negotiations for the mutual good.
I was on the owners side last time around, and as I've mentioned previously he did some good things for the players such as significantly raising the minimum salary (important when ~ 40% of the NHLPA are on mimimum salary), but this is just pure greed and stupidity. Bettman needs to go as point 1 of any new CBA.
