You are missing the point. This is common in the two most successful conferences and no one complains. Big-10 in Indy and the SEC in Atlanta and those fans don't make up every excuse about playing the game there very year. The Big-12 also held the basketball tournament in KC every year but no one was pissed about that. Playing the game in Texas is the best logistically and puts the game in good weather most of the time. The fact that it is hard for people to comprehend that, and the fact that the closest team to Denver is almost 8 hours away is astounding.
Buff fans: We hate playing games at Mile High RG, please get us out of this game, but we are pissed at the Big-12 for not scheduling a championship game at the stadium we hate playing at and showing up to.
I'm going to take a wild guess that you never bought tickets and attended any B12CCGs.
If you had, you'd have seen how truly un-neutral the fan support was when CU played, and it sucked. Part of being an equitable member of a conference is having an equal shot at hosting a conference championship.
The issues with Invesco and CSU is broader than you paint it.
Invesco was fun when the CU-CSU rivalry was initially renewed. But the repetition breed contempt. The tear gas fired by cops wearing riot gear was too much. Getting lectures from the schools about how to properly behave was embarassing.
Over the course of the series, both teams fell from being nationally ranked to just being rank.
The 9-game P12 schedule further put a premium on OOC locations where getting a sixth game in Folsom is tough.
Mostly, though, Denver should aspire to be more of a college football friendly town. If Boise can host a bowl game, so can Denver. The Mile High City doesn't even try to promote itself as CFB friendly.
People from across the country love to travel to bowl games and to exotic locations. Denver should have welcomed at OOC matchup that pitted NU or Mizzou against Texas or Oklahoma. Those football fans would also be skiers and beer drinkers. The Vail Back Bowl at Mile High needs to happen.
I don't think fault lies only with the B12 for pushing the CCG to KC/STL or DFW/HOU/SAN. Some culpability resides with the Denver boosters who have a piss-poor track record on promoting CFB inside the Mile High City.
