Honestly, the closest I've ever come to a moment like that was when Syracuse Basketball won the title in 2003. After what seemed like an eternity of an NCAA tournament, the clock ticked to zero and Boeheim actually started smiling. And I sat there and thought "My team won. That's never happened before". Having been a Bills fan since the 1970s, I guess that's how it's going to feel. Stupefied disbelief.
And then I'm going to get the best damn bottle of Cabernet off the rack, blow off the dust, rinse out the decanter, and savor every last drop.
