Actually, it would be incorrect to say OU is better than NU in both offense and defense because the Blackshirts allowed only 3 pts and even had Baylor made the second field goal it would have only allowed 6 pts. 3 < 7 and 6 < 7, so the Blackshirts > OU.Nebraska's offense scored 13 pts against baylor.
ONE touchdown.
The game easily could have been 13-10, or 13-13 had baylor made that FG.
OU put up 33 against Baylor, and only let them score 7.
I'd say that means their offense is better than Nebraska's, and their Defense is better than Nebraska's.
OU > NU
Offensively, OU > NU
Overall, I'd say OU => NU is more fitting.

Outside of the maths, I'm hoping for a win and think it's possible, just less probable than a loss. I think either way it's close though and I'm looking forward to Saturday night.
