Players in the Book

[Nevadaref]

eventnyc asked if it is permissible to list names in the book of people who are not dressed in uniform. Rather than simply tell him not to worry about this, let's answer his question.
Listing all possible players in the scorebook is a smart coaching move. If by some chance the game were to be suspended and then finished later, only those listed in the book could play without penalty. Therefore, it is justified to do this and since there is no rule against it, it is legal.
Also, if a coach chooses to suit a player up at halftime, then that player may also play without penalty if he was listed in the original line-up submitted prior to the 10 minute mark.
Just consider those not dressed, but on the bench and in the scorebook to not be in proper uniform. Since this is the case, they are not eligible to play until they are properly attired. So yes, they can play with 4 or fewer if necessary and still have these people on the bench.
