Everyone in the Big 12 not named Kansas loves Fran because he goes out of his way to suck up to them in his game calls of Kansas and in his social media platforms. This isn't complicated to understand or recognize. It is simply math. Fran knows there are more people tuning in to watch KU lose than to watch KU win, so he plays up the "KU gets all the calls, you have to beat them by 10 to beat them by 1" shtick because it gets him love from non-KU fans. And it's become enough of a shtick that even opposing coaches are referencing it now.
Obviously you think he is impartial; you like what he's selling. He's been kissing up to ISU fans for a few years now. His twitter feed is littered with pictures of ISU fans posing for pictures with him, kissing his butt about how great it is to meet him. He rolls into Ames and people treat him like a rock star everywhere he goes. He eats that stuff up. You're his audience. Impartial? Laughable. He's a little Italian dude from Brooklyn who loves an adoring audience and who identified how to get one. Good on him.
