Your data is garbage.
2003. Bottom three teams in the league are all from the North. Teams 2, 3, and 4 are all from the South.
2004. Yes, the worst two teams are aTm and Baylor. The next three worse teams? All from the North. Guess what? OU won all of those games. Would have had zero effect of who we played where, most likely. Second closest game out of that group of games was actually a game against winless aTm. They are a South team. Oh yeah, a team from the SOUTH won the league. KU second. South team 3rd. Very interesting.
2005. Conference standings go KU, OU, OSU, & TT. That is North, SOUTH, SOUTH, & SOUTH. Worst team was Baylor. NEXT FOUR WORST teams are ALL from the NORTH.
Like I said, this notion that the South hasn't held it's own is straight garbage. If I had the time, I'd prove it out once and for all, but I currently don't. How about Big 12 records for all teams over the two tenures? Even that is flawed.
Look. This has gotten more heated than I intended. I never expected someone to die so hard on this particular hill. Here are the facts:
1. KU was in the North. Once the Big 12 formed, Kelvin only had to play in Lawrence every other year. During that span of time, KU won at least a share of the Big 12 7 times with three more 2nd place finishes. They never had fewer than 23 total wins, never had fewer than 9 conference wins, had one 16-0 conference season, two 15-1 conference seasons. went to the NCAA tournament every single year including a national runner up, a final four, and two Elite 8s.
2. Baylor and A&M were AWFUL in the late 1990s and early 2000s. Baylor literally had to recover from a murder scandal involving its coach. Baylor's conference record during that period was 41-119 (.25%). They never finished above .500 in conference play.
Thanks to Gillispe coming during Kelvin's last 2 years, A&M's record was a little better at 56-104 (35%). Both A&M and Baylor had seasons where they went 0-16 in conference play. It's just hard to describe how terrible those programs were.
3. We can quibble about a lot of things, but let's put it this way. From 1997 (the first season of Big 12 basketball) to 2006 (Kelvin's last season), he went 39-1 against Baylor and Texas A&M. So was it more advantageous, to play 4 total games vs. those two turds and only one vs. KU (regardless of where it was played) or not? I'll leave that for you to decide.
4. Since Lon has been the coach at OU, Baylor has had 6 NCAA tournament appearances (including an Elite 8 and 2 Sweet 16s) and won the NIT. They have never once had a losing season during that period. I could go on, but I think it's fair to say their program is a little different now than it was in the 1990s and early 2000s.
Look, I'm really not trying to take away from what Kelvin did at OU. It was excellent. I enjoyed it more than most. But I'm also willing and able to recognize that the conference, as a whole, is more difficult than it was back then. It's deeper with fewer freebie wins and more road games. If you want to look at the raw numbers, that's there too---conference RPI, NCAA tournament bids, and on and on.
I can see we're not going to ever see eye to eye on this, but I honestly do appreciate the conversation. It's been fun going back and looking at all this history.
