I read or heard somewhere that the NBA doesn't do their exhibition games like that anymore, or at least not in small venues like the Henderson Center.
I'm old enough to remember when major league baseball clubs broke up spring training in the Florida Grapefruit League and headed back "north" for the start of the regular season. They would stop and play exhibition games on the way back in towns/cities in states up and down the eastern seaboard. Remember seeing Boston Red Sox vs. Boston Braves in Bluefield: two of the players were Ted Williams and a young Henry Aaron, as I recall. On same field where Bluefield Blue Jays still play today.
