I've used the Bills legacy to help me get over SB losses in the past. It was quite the run and I don't think people will forget about them even if we better the feat by doing it with some wins mixed in.
Yes, there is merit in getting to the big game four years in a row. Having fallen short all four times - many of them being blowouts - sullies the "accomplishment". In at least three of the seasons, the NFCCG was the actual Championship...
Bill was quoted once as saying, in effect, that going to - and then proceeding to lose all of them - 4 straight SBs isn't as impressive as others believe.
The Billiards' GM during that time? The drunkard Bill NaPolian.
