I'm thinking more just what pitchers have done while with the Yankees. Kennedy had success in the minors. in 2007 he was successful in 19 innings, but in 2008 with the Yankees he was terrible.
Nova was successful last season, but I don't think he was someone who was a top prospect coming up through the minors.

it’s worth noting how little success the organization has had developing starting pitchers during Brian Cashman’s tenure as general manager. In fact, since Cashman took over before the 1998 season, his system has succeeded in developing exactly one front of the rotation starter.
I have no idea how that compares to all the other teams.
