QB - 1976-1979 - With Staubach and White alone, this is pretty good. When you include Carano, and the fact that both Jim Zorn and Steve DeBerg, both pretty good QBs, couldn't make the team in this span, that's a strong group.
RB - 1970-1971 - It doesn't get much better than Duane Thomas, Calvin Hill, Walt Garrison and Dan Reeves. The Cowboy group in 1980 was pretty good as well with Tony Dorsett, Robert Newhouse, Ron Springs, Timmy Newsome and James Jones.
WR - 1965-1967 - Lance Rentzel, Bob Hayes and Frank Clarke.
TE - 2009-present - Jason Witten, Martellus Bennett and John Phillips. Honorable mention to 1979-1983, with Billy Joe DuPree, Doug Cosbie and Jay Saldi.
OL - 1991 through 1995 - We all know the starters. The impressive thing was the depth. Guys like Alan Veingrad, Ron Stone, Frank Cornish and Kevin Gogan were on the bench. Deep and talented, and set a standard for many years, though it's likely that only Larry Allen will make the HOF.
DL - A tie. 1992-1993 - Same as above. Adding Charles Haley to Jim Jeffcoat, Tony Casillas, Russell Maryland, Jimmie Jones, Tony Tolbert and Chad Hennings gave the Cowboys a terrific two deep unit. The 1965-1974 units had Bob Lilly and Jethro Pugh, along with George Andrie, and other ends such as Willie Townes, Pat Toomay, Larry Cole, and at the end of this run, Harvey Martin and Ed Jones. The Cowboys have had some great linemen in their history. A year later they add Randy White.
LB - 1968-1976 - The starting trio of Jordan, Howley and Edwards adds D.D. Lewis in the beginning of this run, and at the end of it, the original trio fades into the sunset, and Hollywood Henderson, Bob Bruenig and Mike Hegman take the baton and run with it.
DB - 1985 - yes, they were burned a lot. But, for one season, the corps of Everson Walls, Ron Fellows, Michael Downs and Dennis Thurman created as many turnovers and big plays as we have seen from a defense in Dallas. Bill Bates and Dextor Clinkscale were also effective during this year. Not a HOF player amongst the group, but they were a lot of fun to watch.
