If this was one of the American major leagues, that's EXACTLY what the Raiders would be doing - and you know what?
If they moved to Wellington due to stadium issues in Canberra I'd be a fan of theirs right away.
If this was the major leagues they'd have been sounding out cities about relocating years ago, and Wellington wouldn't be on the short list unless they were willing to build a built for purpose rectangular stadium.
Don is too afraid of the backlash of jumping into the relocation discussion that the club needs to have, so he's trying to just dip his pinky toe in instead. He's trying to threaten the government with taking games away without fully committing to it, and all he'll achieve is the worst of both worlds.
Taking the odd game away won't be enough to sway the government or public opinion, and it'll compound most of the issues the club is facing. It'll lower the value of memberships here in Canberra, hurt attendance numbers, and put his supporters offside, while giving a free kick to his political opposition to argue that investing in a new stadium is even more of a waste of money if the Raiders are going take high drawing games out of town, and that they're greedy and only doing it for the cash.
Threating relocation is the nuclear option, but there's no half pressing the big red button.
