Most likely: all of them. Most people have above average taste in some subject they are, for whatever reason, overly interested in. And you can't really judge this based on how good they are now or will be because that doesn't say anything about their taste just their current ability.
It's kinda like your example. No one in Dallas really thinks the Cowboys are any good. Not anymore. It's just something mildly amusing you can say. In fact the comment is rooted in being obviously tasteless. It's just the local team that was really good way back when. Those with taste may recognize that Romo was actually good or that he's made a good commentator but no one actually thinks the Cowboys are or were good since their heyday. (Though honestly I don't know or care about the team. I'm basing this on listening to sports people.)
