I think Mizzou was ranked #12 heading into that bowl game. 2011 vs. Oklahoma we were within a touchdown with the ball late in the 4th quarter. 2014 vs. LSU we lost 21-14, they punted on the last play of the game, a return for a TD would've tied it. The last three have definitely been rough. Playing bowl games against Oklahoma, LSU, Florida, Stanford, Tennessee, etc., there's always the chance of hitting a rough patch. But you're right, big time programs should expect better, even going against other big time programs.
