I'm always interested as to how GMs handle situations like this where there are other bidders but you don't know what their bids are....do you go "all in" right away with everything you're willing to give up to get a player in order to appear the most attractive, or do you inch up your bid in hopes of not giving more than you absolutely have to but take on the risk of losing out to another bidder with a better (at the time) offer? Obviously setting a limit for yourself as to what you're willing to trade is wise, and if another team offers more than you're willing to give, so be it, but the process is fraught with peril regardless.
