At what point do you put in the RF to pitch?

Just like in baseball sometimes it very clear that it isn't your day and you just have to take your arse-kicking. Do the Saints start to sub out some gimpy players to make sure they're available for Carolina? Regardless of what happened tonight, that game was/is going to be much more important. The inside track to homefield advantage wouldn't have meant a whole helluva a lot if the Saints couldn't win their division.
