I think that Portis is a must. Especially at home against KC. With Campbell throwing, I think they'll want to use a ground attack a lot against KC, and throw only if necessary in the end. I don't think his injury will limit him too much on Sunday.
As for the second choice, I have to think that Slaton will do better in Cincinnati than Rice will do in Minnesota. Both are traveling against pretty tough defenses. I say Slaton.
Portis and Slaton. Good luck!
