The relationships between the various heads of the league evolved naturally from distrust, dislike, and competition to one of grudging respect.
What I didn't like
If the show were to be expanded, I would add some focus on the perspective of the players. What it must have been like to be playing to crowds of 100,000 people, and their feelings about the game itself. We do get to meet Jackie Robinson as a character, but he, of course is a force of nature unto himself.
My overall impression
The play does a great job illuminating the meteoric rise and fall of the negro baseball league from the perspective of the business men and women who made it happen.
