No matter how attractive a guy might be, at times he needs a wingman. The job of the wingman is to occupy the other girl(s) who came with the girl his buddy is trying to impress. The wingman, by definition, cannot be more attractive or charming as his friend. His sole purpose is to ensure his buddy has the full attention of the girl he wants to meet.
On an NFL roster, the kicker is the wingman. He is that guy who is not required for the team to make the love connection, i.e. win the Super Bowl, but he serves to ensure there is a greater opportunity that it will happen.
