Slideshows are just ways to try to get more "hits" to a website as a means of conning advertisers that a site is more popular than it really is. It would be like if you had to order that pay-per-view movie every 20 minutes to keep watching.
If the list includes Denver, I would disagree. The Broncos have two SB rings in the past 20 years and a couple of Stanley Cups plus one NL pennant. Now, if you want to include CU on the list of Denver teams, maybe they can make a case but I think Denver fans have a rather normal fan experience across the four major sports.
I miss the old Mile High Stadium.
