No
Warner/Alexander >> Bledsoe/Faulk
Reasons:
Bledsoe is a beginning of the year QB, and he also has the Dolphins and Pats in his division, two notoriously good pass defenses. Once the season changes in Buffalo, Bledsoes numbers will drop. You've got to look at how you will win in the playoffs in FFL IMO, and Bledsoe is not the guy to do it.
Also, Faulk won't play in all 16 games this season. Scenario A: Warner and the Rams come back to life and dominate their weak division, Marshall is held back in last 3 games. Scenario B: Marshall suffers nagging injuries throughout the season, highly likely when you look at Marshalls past. He only has 3 seasons where he played every game in his entire career.
Warner will be sharp this year. He'll provide plenty of points on his end. Alexander is more of a stretch, but you have to look at his improvements. The Seahawks say that Alexander will be more involved in the passing game. Shaun also has a great O Line, and offensive firepower. He is a durable back who will get EVERY carry. Shaun has great potential this year looking at his very weak schedule.
my opinion, stick with Warner/Alexander. Of course, it is fantasy, I could be 100% wrong.
