you have the same ultimate goal, but you have to have a realistic perspective of the quality of your team and how close or far they are from achieving that goal.
you think a team that goes 1-15 the year before is the same quality as a team that goes 15-1, and thus both teams should view themselves identically? of course not, but that is the corner you paint yourself in when you say every team should view the performance of their seasons identically if they don't win the Super Bowl.
a team that wins 3 games one year and 11 games the next is going to look at that 11 wins differently than a team that wins 14 games one year and only 11 the next. if you can't tell the difference between those two hypothetical teams and think everything is even than you have a severe lack of perspective.
