I apologize for any confusion I've caused. It took so long to get this league going I found I no longer had a tight handle on my own rules.
1. One-point letter players do not have to be "scrubs," whether extra letters or not.
2. If your player's name is worth more than 25 Scrabble points, then you can discount any letter's numbers so long as you use all the letters in the player's name.
