A few popular points:
-The refs were super biased for BYU. They wanted to see BYU win.
-BYU is full of thugs who are constantly taking cheap shots
-The loss was probably good for the Zags
-this was a fluke.
There were also quite a few people giving credit where it was due. Not much humor over there today. Zag's are a good team and a fighting BYU team pulled it out.
