Do not trade Housh when you'll be left starting Chambers. #1 he isn't very good. If you take away td's he'd be having a horrible season and td's can be streaky. Take into account that Gates & LT will get healthy and take more of them and it's even worse. #2 he's hurt and out this week at least.
You have good starters but a pretty poor bench. I don't think I'd be looking to trade too much with that team unless you find someone with 2 good qb's willing to do something like Housh and Campbell for Warner and a decent #2 wr.
