Aggie fans were eager to join in the fun, even those that weren't watching the game. @emiliescribbles tweeted: "My favorite part of tonight was being in Smith's and hearing someone update shoppers on the Aggie score over the PA. #closeknitvalley"
@alyse71 put her own spin on the well-known USU chant: "I BELIEVE THAT WE HAVE WON!! #aggies #USU"
Utah supporters, on the other hand, displayed a range of emotions, from disbelief to despair to realism.
Utah fan blog @BlockU tweeted: "Utah totally outclassed. Whittingham totally outcoached. Utes totally outplayed."
@CarolinaUte had this observation: "Folks, the loss tonight is why some #Ute fans shouldn't talk about going to the Rose Bowl prior to playing/beating credible opponents. #fail"
BYU fans couldn't help taking a few potshots, either. @GeoffJBYU had this to say: "Dear every BYU fan telling me to not get overconfident about the Utah game: Save your breath. BYU is better than Utah this season."
As for the national scene, Sports Illustrated writer Stewart Mandel tweeted: "Texas State. Utah St. Almost San Jose St. ... Can we give it up for the WAC?"
And ESPN.com's Pac-12 blog didn't use some questionable penalty calls as an excuse: "Homecooking officiating late? Absolutely. Excuse? No way. Utes shouldn't leave themselves in that situation."
