I think we are weaker on paper at every major position grouping as compared to March 2012.
Maybe we'll improve via the "chemistry" angle (i.e. we got rid of some bad apples). Maybe we improve with better health and less starter games lost.
But talent-wise, I don't think there's any doubt we are much weaker than 365 days ago. The draft will help, but not in 2013 based on recent history. If we get 500 snaps total out of the draft (not injury replacement) then that's pretty good. If rookies are playing because of injuries, then you aren't improving via the health angle.
I think we're a borderline playoff team right now with very little chance to make a good run in the playoffs. The ceiling for this team is just too low for my liking.
