Fantasy Football Needs One More Statistical Category

I'm not sure I know of a league that does this, but I came to the conclusion last year that when counting points an additional category should be added. If the player's team wins the game, additional points should be added...say 1 or 2 points. The way most leagues are set up you could load up with high stat players on bad teams and win your fantasy league. I guess that's fine, but the object of the game of football is to win. Shouldn't a player be considered better if he helps contribute to a winning effort? Some guys might have more impressive stats than others, but their padded stats might have helped contribute to their team's loss. If we are to have any room to value the guy who sacrifices a few stats for the betterment of the team, there must be a way to reward that statistically. The only way I know how is to award points to the players whose team wins that day. What do you think?
