No... it really wouldn't. Katz won't be substituting his champagne for sparkling wine any time soon, and with a draw like McDavid, there will always be a waiting list.
There's only one way to sway a billionaire, and that's by publicly embarrassing him. Any kind of protest that will make headlines on all the sports shows, and become a topic of conversation in the hockey world, would most likely do the trick. (Suggestion: Off the top of my head, large signs or a billboard reading "SELL IT TO SOMEONE WHO CARES, DARYL", complete with a picture of his face, of course). Stay away from something as unremarkable as "Fire Chiarelli' (though that's the goal)... to make waves it must be clever, memorable, personal, and embarrassing.
A few dozen determined season ticket holders could have Chiarelli finally booted into ECHL obscurity in a matter of days... but alas, like the owner himself, few of them really care about the hockey.
I could really change the world... if I cared. - Ricky Gervais
Something to the effect of "We were going to write something shaming Chiarelli on here, but then we realized his body of work was embarrassing enough" with a big QR code to a list of his trades on one side.
