The Miners are an expansion team. Of course there's no rivalry.

You could easily have a rivalry as an expansion team, if there was another team in the league that is close geographically. For Pikeville, imagine if there was also an expansion team in say, Kingsport TN or Charleston WV. Pikeville could easily market a team like that as a rivalry game, in order to draw in fans. I remember when the Louisville Panthers of the AHL were created by expansion, they immediately became a rival to the Kentucky Thoroughblades (who were based in Lexington), simply due to geography. But the closest city to Pikeville in the CBA is Pittsburgh, then Atlanta, neither of which is close enough to be considered a rival.

Once again, the point I've been trying to make is that seeing teams from far-away cities that many have never heard of will not draw in large crowds.
