Gonzo for McMichael would be a very good trade for you. '
I think you're sitting pretty at RB. Of course it would be nice to know that Gore was the starter for SF. I think he will be, but don't know for sure until the season starts.
You must have faith in the Skins D. I don't think they can do the same good as the past couple years. Also keep in mind that they are not an opportunistic bunch. Decent stat wise. Might be okay if you couple ST's in with defense in your league... but other than that I'd try to get out of that mess!
You're welcome for the $.02
