JG, It matters not what letters fill your 9 spots in the L/U, that said L/U needs only to be in Alphabetical order. There's no limits on letters, it matters not what last name the lead-off batter has, you can skip letters, anything,,as long as your L/U is in Alphabetical order.
The fun and insanity of this league is in the make-up of your draft cards and moves post-waivers. It's going to drive you nuts. :D
