The circle is only there next to the player's name while the Amateur Draft is going on. It'll disappear after the Draft.After the Draft, look at Sign Draft Picks. It'll list the players you drafted and the other 29 teams draft picks if you're in 30 person control. I always mean to write down the names of all 150 draft picks so i don't scout them again, but I never have the patience. I just make sure not to scout my draftees twice.
