I don't fault the producers for trying something different and opening a show in May. And it's certainly not the only show to have done a summer opening: Boys in the Band, Act Of God (twice), 1984, Hamilton, Harvey, Master Class, Hairspray, etc.
The schedule was also based on timing. There weren't any open play houses before the Tonys. The two leading actors (who have been signed on for about a year and a half) might have been busy before the Tony cutoff.
