I appreciate the reply and agree with your comments.
Even though the remaining free agents generally ****, signing up enough to fill your roster also gives you an opportunity to gamble on a player who might surprisingly improve in areas that you covet/need. Or simply to experiment with player weights/skill sets. There is no cost to doing so if you sign them up for a year (no bonus required) or you can give them a minimum bonus for multiyear contracts.
Good luck with you search.
