eesh, is your opponent this week good? If so i'd stick with Brees. If you can afford to risk it, play Carson
I wouldn't sit Brees this week. Two Jets CBs are out for the game. Plus Cleveland has the #16 Pass Defense in the League. Meaning they're middle of the pack. They give up a ton rushing, but not as much passing. I think Palmer could put up decent numbers, but I would not start him over Brees.
