re: Who Should I Keep?

I would more so characterize Julio as a top 6 pick. Regardless I would still say that he is definitely one of the elite tier players, and you are probably not replacing him with a player of his caliber in a keeper league. But I think it is possible OP is able to replace Julio with one of the other elite tier players with his first pick depending on where he is picking in the first and who the other people in his league are keeping. If that is the case then he let's Julio go and keeps one of the other players. If it isn't the case or there is much uncertainty then you keep Julio. In my opinion.
