You contact WIS.let them know the league parameters(Season).Somehow they load ALL 1946 players.it works like this.I am sure other owners can explain better than I.let's say in round 10,I wish to draft a catcher.I click on catcher position and the utility lists all the catchers that have been drafted.if I try and draft a player that has already ben selected,IMMEDIATELY the draft utility gives a message saying PLAYER HAS ALREADY BEEN SELECTED PLEASE PICK AGAIN.or something like that.The big thing is duplicate picks which happen in 1st year drafts are completely eliminated.
