I, too, am a Yankee fan. For many years, I have wished a hard cap for MLB. As much as I enjoy the winning and competing for a ring every year, it got stale. It was expected. It took the fun out of it. You can't possibly enjoy the success to it's fullest knowing you have the upper hand on the majority. (Before Sox Nation jumps on, SCREW YOU, you're 2nd in line in payroll)
To answer your question, it would not effect me as a Bills fan. Conversely, as I pointed out above, (Cowboys/Redskins = Yankees/Sox) I would hope the Cowboy and Skins fans wouldn't be dancing in the streets should we learn the NFL goes uncapped. It is not good for the broad base of fans overall. The perennial loser as well as the perennial winner.
keep it fresh....keep it real......
