If it's a Doug Gilmour jersey and autographed?

I came across such an artifact and it is ridiculously priced (on the good side of ridiculous) but... Sabres. I need a ruling. Does this violate the "one team" idea? The unspoken "don't buy anything to support a divisional rival" idea? The general "fuck the Sabres and everything associated with them" clause that comes with being a Leafs fan?

All good questions, but... it's Dougie Gilmour and i live out in Saskatchewan where there's next to no chance to run into him so he can autograph my Leafs jersey.

I await the ruling of this esteemed council of fans.
