I think the “married w/ kids” line doesn’t actually necessarily help the small markets. If you’re a single guy, you’re on the road half the season and can get your fill of the club scene in then. You’ve got the whole offseason to jetset and go wherever you want.
However, the family members are the ones who are stuck in the home city all the time, who have tons of free time and maybe not much to do. KD liked Oklahoma City. It was his mom and brother and other hangers on who wanted to get the hell out of there.
