I hate the threats and strong-arming as much or more than anyone else, and Bettman is really being a jackass, but-
all Hamister appears to want is help with the arena. Some of it might have already been on the table for Rigas, too, so what's the big deal?
The tax $$ to invest into the arena is more than worth it to keep the team alive and well and maybe enhance the arena's usage.
It's a no-brainer- the area must commit.
