Not sure which hurt more, they were different types of pain. '98 was the better team, that much closer, lost in a game it pretty much dominated, and did all of that in horrific fashion on my 15th birthday. But the '12 team may always be my favorite. Even if when we win one, it will be bittersweet knowing Collin, Arthur, and Chris and that group (and most likely Bill) didn't. That team (tucks in shirt) exemplified K-State and "the Snyder way" as well as any team; it would've been the perfect culmination of events. I can't imagine a more story-book ending. (Untuck) But that team was beat soundly twice, so that eases the pain a bit.
I don't think it's been mentioned, but I remember seeing Ell on the turf holding his hand during the McNeese State game and feeling a sense of dread that something special that was going to happen wasn't going to happen anymore.
Since I'm now in full wallowing-in-sorrow mode, Butler still really stings, too.
