To those who select the 1977 Cowboys defense over the 1971 defense, I respectfully have to disagree with you:
Note: You cannot go wrong with either defense; both were awesome.
However, here is why I take the 1971 Cowboys:
They were a little more veteran group. I believe there was a little bit more camaraderie. They knew their assignments a little better.
The 1971 team was a little frustrated during the first half of the season. This was due to the quarterback controversy primarily. Landry couldn’t or wouldn’t make up his mind. That wasn’t the defenses fault though.
(Had Roger been selected as the starting quarterback in the beginning of the season, then there is a chance that it would have been the Cowboys having a 17-0 season – and this discussion would not be taking place)
The defensive line comparisons I believe are a wash. The 1977 group had a little bit better pass rush, whereas the 1971 group had either the #1 or #2 Rush Defenses in the league for the fifth time in the previous six seasons. That, my friends, is sustained superior performance. Martin, White, and Jones on the pass rush was just freaking incredible though. Larry Cole and Jethro Pugh played on both teams
(Also, if there was ever an unsung hero in Cowboys history, it is George Andrie. Don’t sell this guy short) - (Oh yeah, Bob Lilly was on that defensive line too. Who can say “29-yard sack?)
The linebackers heavily favor the 1971 group. There is just no comparison between Bob Breunig and the great Lee Roy Jordan (why isn’t he in the Hall of Fame?). Chuck Howley (1971) and Hollywood Henderson (1977) wash each other out despite being totally different. Both were fabulous playmakers. Dave Edwards I would give the slight edge over D.D. Lewis (who was on the bench in 1971). But it is Lee Roy Jordan that really tips the scales here.
The secondary also goes to the 1971 group. Waters and Harris were spectacular in 1977 as that legendary safety tandem. However, they were both on the 1971 team as well, with Harris starting. Randy Hughes was an up and coming replacement that was great in 1977, but injuries shortened his career. Benny Barnes and Aaron Kyle were good corners, but not great.
What tips the scales for the 1971 secondary was HALL OF FAMERS Mel Renfro and Herb Adderly. Cornell Green and Cliff Harris were fabulous as well, thus rounding out the Greatest Secondary in Cowboys History.
Last note: Miami’s offense in 1971 (Greise, Czonka, Little, Warfield, Kuchenburg?) was better than Denver’s offense in 1977 (No hall of Famers there).
