I think I would just stick with Palmer.  He has 600 more yds and 4 more TD's then McNabb already.  Yes, McNabb had a good game this week, but I like a healthy Palmer more then McNabb down the stretch.  I wouldn't be too worried about the matchup against Baltimore as far as winning this week is concerned- he threw for 270 and 1 TD the first time around and that was on the road.  Look for even better numbers when he faces them at home.
