Worst field I've seen since 2001 Notre Dame. This HAS to be done on purpose. A local lawn care service could create a better surface than that. Last week it was even longer and shabbier and ½ dead looking. In 7 days it was bright green and slightly shorter, but the surface was absolutely horrific.
If this was not a purposeful setup by Oklahoma in order to gain an advantage, then their entire grounds crew needs to be fired immediately and replaced. It's September for goodness sakes, there's no reason for this grass to not be anything other than spectacular on game 4 of the season in good weather!
