I can only really come up with Detroit. Denver could but that would only be "who's the best right now other than the Broncos", and not an "always" case. If they were to get an NBA team I could make a case for Pittsburgh and even that is only because the Pirates have been so awful for two decades now (I know they're good this year). Historically though, the Pirates would still trump the Pens. Any other 3-big 4 cities, were they to acquire the missing one however, I don't think it would happen in. You wouldn't think it, but in Detroit its Lions #1 and what ever team is doing better at the time for #2 That seems rather ironic, doesn't it?
