I think your starters are solid. I really like Colston and Ochocinco this year. Both are due for a nice bounce-back season. Bush is a great backup, if he can stay healthy. Not sure if McClain is going to get enough touches to actually accomplish much, but might be a good pick when McGahee goes down again and frees up some room in the RBBC. Favre is an educated gamble, so you might get some good backup numbers there when Rodgers is on a bye.
Take a look at mine if you get the chance: viewtopic.php?f=44&t=441506
