I think they did something similar or the same last year maybe even several years in a row IDK.
I do agree with you. It's their thing to give and it's no skin off my back but it's not exactly across the board fair.
Take KC for example. Had the Chiefs been in they would have to award the entire KC metro which is both KS and MO not just MO. There are a ton of Chiefs fans and ticketholders on both sides of the state line. And had the Rams still been in MO it's split on who are fans and who aren't. If you were living closer to STL you'd be a Rams fan, you live closer to KC you'd be a Chiefs (*Rough estimates here). Then NE is a multi-state region.
In the end it's not really a huge deal, drums up good enough PR, etc but it's not exactly a fair shot.
