The National Football League (NFL) season is starting tonight, so fantasy football players across the globe should have already drafted the teams they will be loving, hating, and generally laying their hopes upon for the next 17 weeks. The rules are simple: draft a team of real NFL players, score points each week as those players accumulate statistics in real games, then tweak your roster via trades and additions to account for injuries and poor performance. Rinse and repeat until the season is over.
