Re: Rate my team...
When you have Peyton Manning, you really shouldn't ever carry another QB other than his bye week. I'd try to package Brees into a trade as well and upgrade your RB spot.
Same thing w/ Defense. I'd never carry more than 1, unless my regular defense was on bye and I thought they were good enough to protect. I doubt youd could use either defense to sweeten a deal (unless you've got an indy or washington fan in your league), so you'll probably have to drop them for roster backups.
I doubt you'd be able to get much in return for either Brees, but he might be enough of a sweetner for another coach if included w/ Bush to get you a better RB.
