Another way to get around the parking issue is free transit for ticket holders - show your ticket to a bus driver or fare inspector and no need for other fare. You let this be active for, say, 90-120 minutes both before and after the game (perhaps even longer after, to boost business for bars near the arena).
A number of cities do this successfully. Those driving from out of town can park at the perimeter, and those in town have less incentive to drive.
