I would have kept Houston's D.
Jamaal Charles is RB by committee with Hillis... so his fantasy value takes a hit... so that may not have been a bad move.
Frank Gore is getting old... so don't expect the same production out of him.
I think you're going to be starting Ben more than Cam this year. Cam is still relatively unproven and the Steelers schedule is a little softer than previous years... plus Ben's weapons are all in place and healthy. Cam was awesome last year, don't get me wrong... but I wouldn't put the weight of my team on the shoulders of a second year QB. Expect inconsistency.
Mike Wallace is a decent choice, but I think Antonio Brown is going to be getting more targets this year because Wallace will be wearing CB's like garments of clothing all year.
Fred Davis is my dude. I really think he's a better start than Celek, especially since he actually has someone throwing to him this year... that is if he can stay healthy.
Foster is a solid start... but during your bye weeks... Shonn Greene is gonna stink it up for you. I think he's an awful starting RB on a terrible offense.
I honestly think the rest of your WR's are mediocre... but they will all give you consistent numbers. Other than Wallace, you don't really have any explosive wide outs.
