If that tweet the U put out is bashing the Vikings, I shudder to think what anything more strongly worded would be called. Honestly, the UMN tweet didn't call out the Vikings, its fans, their play, or anything else. They were referring to the success of their own team by highlighting the fact that MSP actually has a football team that plays on a national/major level that's winning right now.
For all the Vikings apologists who come here and whine that certain Gophers fans get too worked up with the Vikings and how they've negatively affected the U's ability to succeed by saying that people can be fans of both the Vikings and Gophers, spend money/time on each, etc and that everything can co-exist... That's great until you remember that the media in this town has downplayed Gopher successes, ridiculed the team/AD/fans (making them the socially-accepted joke of the town despite middle-of-the-pack play over the last 14 years, minus 2 Brew years), and flat out given little to no coverage when not doing the previous 2. This is just another example of their overreaction and negative coverage of a completely innocuous tweet.
