Should I trade Marion Barber for Darren Sproles & Roy Williams?

Hell no dude Darren sproles is a decent handcuff at best and Roy williams is no longer the best reciever on his team... meanwhile marion the barbarian is one of the most effective goalline backs in the league meaning he is going to get a shot at scoring at least 1 if not more TD's a week... with the way the dallas O is playing it wouldn't be wise to trade one of their studs...
