With the National Football League set to kick off its 2013 season with Thursday night’s visit by the Super Bowl champion Baltimore Ravens to Denver to take on the Broncos, fantasy football players who have not yet joined leagues have another option in the form of Facebook application Unbenchable.

Unbenchable allows users to input their lineups for each week and compete against their Facebook friends. Players can issue challenges to as many friends as they want.
