The WW can be your best friend or your worst enemy, because I've turned a few losing teams playoff teams using the wire and have sometimes gotten creamed using the wire. I generally only use it to pickup low PA high production players in exchange for dead weight $200K scrubs, but I also have no problem dumping a an expensive supposed good player that I drafted who is underperforming. For example, I recently dumped 15 Cravath who was hitting about .220 and with few HRs at nearly the halfway point of the season for 1899 Buck Freeman who promply hit about .320 and clubbed many HRs. For me personally, success using the wire is more a matter of identifying the right player for your team in relation to the kind of player you want to dump. Sometimes it works, and sometimes it doesn't. But the key is to be patient and pick your spots wisely.
