Success in the NFL can often be misleading.
Yes, wins can tell us a lot, but everybody knows that a good team can catch bad breaks and wind up with more losses than they deserve. Playoff berths as a measuring stick? Sure, but who's to say that an 8-8 division winner is better than an 11-5 team that got squeezed out of a wild card spot?
The point is that subjectivity can play a big factor in how teams are valued -- how good or bad they are.
At numberFire, though, we try to eradicate subjectivity and see what's happening in terms of sheer numbers.
