Responding to the comment above about Ratmansky using ABT's home grown artists:
Frankly, I think part of the reason Osipova and Vasliev decided to join ABT had a lot to do with Ratmansky. He was their champion when he was artistic director of the Bolshoi, and he promoted them to principal there. Ratmansky gave the lead role in Firebird to Osipova (with Misty in second cast). He also carved out leading roles for them in the Trilogy last season. Obviously, those ties ultimately were not strong enough to prevent Osipova from leaving ABT for the Royal. We'll see what Vasiliev's future plans are.
Also, the incredible period when Ferri, Ananiashvilli, Vishneva, Corella, Carreno, Bocca, Steifel and others appeared nightly on the Met stage was under McKenzie's leadership. None were "home grown" at ABT, but those were spectacular years when ABT was the envy of every ballet company.
