The Sabres are a drag to his bank account.
How much do the Bandits make for him? Being a niche sport, I can't imagine it's significant.
As was mentioned earlier, it may be a matter of him not finding anyone to buy the Sabres and keep them in Buffalo. He might be waiting to get those expansion fees and then sell, I don't know.
And there's no way he "gets his thrills" with the state of the franchise. Hockey is his true love.
