Agreed that your RB depth leaves a little bit to be desired. Other than that, though, I really like your team - you got a top option at QB, a solid and deep WR corps, a TE with some serious production upside and you waited until the end to grab your K and DST.
About my only suggestion would be to consider dropping James Jones and Ricky Williams for some upside on the wire. In a 10-teamer I have to think there are some guys out there who are better lottery tickets - if you list your best available FAs, I'll gladly make some recommendations ...
As things stand right now, I'd probably give you a B+
Hope this helps
