The NCAA's most odd deficiency is its unwillingness to incorporate stats THAT WE ALREADY KNOW AND HAVE into the official records. Bowl games, sacks, FG %, etc. going back in time are widely known and if not, kept by the universities themselves.
I consider myself a relative expert on this, as I've had to deep-dive over 1,600 teams going back 50+ years for this stuff.
Take Miami....they have PDFs of every game going back decades that include sack numbers. PDFs of the hand-written, day-of-the-game totals...those aren't faked. They may ebb and flow when it comes to accuracy, but when a sack happened, the guy keeping track put a 1, or a 1/2 next to 2 names he'd written in himself, because those were the players on the actual field that day.
Would it kill each athletic dept to grab some kid and have him go through it all for season totals? No, that'd be great. But the NCAA just sits on its ass, even when these stats are well-known.
It's truly bizarre.
