Kentucky is one of the bigger states without a major pro team in baseball, basketball, football, or hockey. I think Tennessee has two already. So I agree with Genghis that they'll be next on the list, though maybe it'll be baseball first, given the whole "Louisville Slugger" thing. The one problem I'd foresee with a northern Kentucky site is that Cincinnati organizations will want to keep their regional base. This was a big problem with the establishment of the Nationals in DC, since the Orioles made a big stink about having another team so close.

Kentucky might be a candidate for a team. If Tennessee can do it, so can Kentucky.
