While its true that our talent falls off after a dozen or so players I'm not convinced that our roster is significantly different than most of the NFL teams.
Few Cowboy fans follow other teams closely enough to know the quality of their talent from 15 through 53. The grass often looks greener.
Further, I have often suspected that your top dozen or so is what covers the shortcomings of the rest of your team.
Aikman, Emmitt, Irvin, Haley, Allen, etc made Robert Jones, Jimmie Jones, Harper, Larry Brown, and a host of others look talented beyond what they were.
Do I think only the top dozen are important? Absolutely not. Do I hope we work tirelessly to strengthen 13 through 53? Yes!
I'm only suggesting a little push back from "OMG - we're a mess from 14 on..."
