Golden Boy

This series is about a young cops incredible rise to becoming the NYC Police Commissioner and we were all ready to do 100 words on "Golden Boy" not being "The Golden Child," which we find terribly upsetting.  However, after contemplating it more, we lament the fact that this series airs on the same network as "Blue Bloods" which features a family of cops including the NYC Police Commissioner.  But that commish isn't the same as this commish.  How does that work?  How do you do the inevitable crossover event?  Is one of the NYC's depicted NYC-1 and is the other NYC-2?  Are we going to get an "Infinite Crisis" style problem?
