I wish I had your problems. I would go first of all with Moulds as a no brainer. Buffalo is pass happy now that they have a QB, and Chicago's secondary is not as great as you said they were. They lost McQuarters (there best pure coverage guy) and the Bears are better against the run which will force Buffalo to throw (as if they needed to be forced).
Secondly I would start Kevin Johnson. He has been great so far this year. They are playing Pittsburgh, but as both the Patriots and the Raiders have shown already this year, the way to beat the Steelers is to pass, pass, and then pass again!!! With all that passing I think the Browns number one WR is a must start, especially since he is Couch's favorite guy.
