Phil Steele looks at this every year in his preseason magazine to see who might have over-performed or under-performed.
Total Offense vs Total Defense in Big 12 Play (games remaining in parentheses)
Oklahoma: +144.4 (@WVU, BU)
West Virginia: +133.0 (OU,
@ISU)
Iowa State: +113.3 (@UT, WVU)
Oklahoma State: +57.4 (TT, @TCU, @BU)
TCU: +13.3 (@KU, OSU)
Texas: -33.8 (ISU, @KSU, @KU)
Baylor: -50.4 (KSU, @OU, OSU)
Texas Tech: -67.7 (@OSU, KU)
Kansas State: -103.2 (@BU, UT)
Kansas: -246.4 (TCU, @TT, UT)
Texas's numbers in that department will improve just based on who they have left to play, but I'll be surprised if they end up better than +30 yards per game on average. That translates to about a .500 record, maybe a game above, on average.
