The way the favorites covered double digit spreads during the middle of the season, I am just very CAUTIOUS. Maybe the "parity" has vanished because teams have learned to deal with the salasy cap - and that separates them from the teams that just can't deal with the salary cap.
So it seems that the parity that the salary cap was supposed to bring has created a disparity because some teams just don't know how to go about it from a management's point of view. Compare the Deadskins to the Pats and there is no better example.
