You must act interested in the not so attractive friends and divert their attention so that your buddy can make a few shots at the goal. So swallow your pride and take a hit for your buddy. You know that he'll do the same for you later. Guys, the best wingmen are the ones that will get on any woman they see. You know what I mean.
Every guy knows one, and they are a very valuable asset in the beginning stages of the dating game.
The more distracted the goalie is, the better the chances for your buddy. In the best of situations your wingman may even take a liking to the goalie and take her on for himself. This is a very fortunate sign, and really helps out. In the special circumstance where there is no goalie present, the wingman takes on a new responsibility. You have to talk up your friend, even if she seems interested in you.
