Todd: Soup Nazi was played by Larry Thomas, and there is a y reliever by the same name, but you don't have to use him as one of your 5 "name" guys under requirement #1. That's 5 Larrys or Thomases unless you can find a player named Yev or Kasem.
Kleine: For Steinbrenner, I think we should go with Larry David who voiced him, as we only saw the back of Bear's head. I hope this is not a problem for you.
Don't forget to state DH, no DH, or don't care as your choices.
