You forgot to mention our best RB.... DENARD!!!!
Ha ha... all kidding aside I see your point. I think Fitz is the #1 no doubt. I bet we see a lot of Rawls this year. Cox gives us some depth but mostly just experience in case we absolutely need him. as mentioned, smith is a situational back. Don't get me wrong, I love V Smith but he's just doesn't fit the system. I'd like to see Hayes get some time but at this point I'll be happy with a guy who doesn't turn the ball over and can be used to keep the safeties and LBs honest. That may be the most valuable thing an RB can give us at this point.
