I think several years ago I thought about the whole head-to-head record issue and came up with this. In order of most to least important:
1) Most recent scoreboard: current state of the team (doesn't really apply currently, but sips, 2011)
2) Record in the last 5 years: current state of the program (doesn't really apply currently, but sips 3-2, 2007-2011)
3) Record during your own lifetime: how you've personally witnessed the rivalry (tied; 15-15)
4) Records since 1975; new era of scholarship limits, further race integration, closer school enrollments sizes (Ags; 19-18)
5) All time record; overall history of the school programs (sips 76-37-5)
6) Best Little ***** House in Texas (Ags got to bone hoors)
Seeing as we haven't played in nearly a decade, none of it means jack ****, but still usually what I go by. I almost hope that we meet in a high-profile bowl game just to claim scoreboard, break my lifetime tie, and of course, because BTHOtu
