I got the following question. I will answer it here so there is no confusion going forward...
Question:
What constitutes an illegal player and allows you to repick? Is it only someone already drafted, or would this rule also cover if I take a player I can't legally roster?
Answer:
If you draft a player who is already taken, a re-pick is needed.
If this is in terms of taking a player that can't legally fit on your roster (due to years or franchise restrictions), you will have to wait until the end of the draft to replace him. I am not monitoring each pick to see if it's legal for your roster or not. Only when it's time to turn in your final roster, will it be determined if you need to replace a drafted player (in order to make a legal roster).
It's up to each owner to keep track of his roster construction and draft wisely.
