Very sad. I'm older than most of you, and I cried when the Cowboys, with Thomas, lost to Baltimore. Thomas's end zone fumble was recovered by the Cowboys, but . . .
I LOVED his running style, and LOVED how he shredded the Dolphins in the next year's Super Bowl. There was a major culture chasm between him and Landry---Duane was on the front side of the civil rights envelope, Landry still on the back side. Landry just didn't understand the big deal coming from his background. Obviously, though, Thomas was really good with Dallas, and came in at just the right time to replace the injured Calvin Hill.
Very much a part of "the" Cowboys legend.
