I still thinks it's a bit unclear. Are you trying to ask "Who is the only player to have played for, and only for, the four teams originally based in New York?"
Also, the steals question, suggest specifying if you mean in a year or career.
Agree. As written, the New York question has tons of answers. David Wright, Derek Jeter...anyone who played their entire career for one of those four teams fits the answer. It needs to say "the only player who played for all four of those teams *and* no other teams."
