Looks like Cal is ok with the NBA coming to Kentucky possibly:
The only downside is I don't see it having much of a benefit to the NBA to relocate a franchise or go through expansion to Kentucky. Most UK fans in general don't follow the NBA and at the most only follow Kentucky players in the NBA.
It would have a benefit though to both Calipari and Pitino in that NBA scouts would constantly be around. If you needed anything else to appeal to recruits, there you go.
