Remove Smith from consideration.
Bush and Sproles are like the same guy, flip a coin - I don't see either having much value going forward unless your league awards points for return yards.
Neither guy can handle a full load, both are situational players.
Both guys will have a big game here or there when they either return a punt or kickoff for a TD or break a long catch for a TD - but good luck picking which week that will be.
IMO, Bush will see more snaps on offense than Sproles from here on out, and I like the Saints offense a lot more than SD's if that makes a difference.viewtopic.php?f=19&t=455505
