right now, the leagues are 15/15. I don't think they do interleague, so that means an idle team every night like it was in MLB before the Astros move. Why not go 16/14 and buy/move Vegas? If no one really wants to be there, then you'd think moving it might be possible. Why not a straight swap of Richmond and Vegas? Is there an AA league Vegas (Former Richmond) could join?
It's actually 16/14. PCL has 16 teams.
