It is definitely more balanced now, but it has been a competitive conference since the mid 1980s thanks to Wayman Tisdale and Danny Manning. If you're going back 20 years, we pretty much knew that we would start out no worse than 5-1 against TTech, Baylor and aTm...and we only had to play Kansas once. That said, there were a lot of tough games because Eddie Sutton had OSU playing at a higher level than they are playing now. Texas was better 20 years ago as well...those were 4 tough games and we would be happy to win 2 of those. We would also be happy to go 2-2 vs. Kansas, Missouri, ISU and KSU. Nebraska always gave us fits as well, but we'd usually beat Colorado.
Again, it was a tough conference back then. Now, there simply aren't any easy games which you can circle the calendar and say "that's a win". Regardless of conference strength, most of us have had enough of squeaking into the dance. We went through this in the second half of the 90s as well, but couldn't help but get the feeling Kelvin was slowly building us back up (which he did). Most of us aren't getting those same vibes now.
What would you consider a quality season for a league overall? If they get 50% of their teams into the NCAA tourney?
