The most I've ever seen is some 7th rounders.
I only know...because I usually pick my teams 1st round...then sim the rest.
I then go in after ST of the following year and check the ROSTER FOUNDATION screen of each team....find their picks round by round...and edit them down to a decent starting point(my opinion of one) for a rookie player and their names and appearances(just my own little neurosis)...and I don't think I've ever seen a round 8 guy.
