Ed Werder talked briefly about DeMarco Murray's durability with Fitzsimmons and Durrett on ESPN Dallas 103.3 FM today.
Murray has missed nine games because of injuries in his brief two-year career.
In comparison, Emmitt Smith missed a total of seven games in his career with the Cowboys and none his first two seasons. Tony Dorsett missed just 10 games in his career, none his first two season,s and three in the first five years of his career.
You could say, well, Dorsett and Smith are Hall of Fame players, and durability is one reason for their success.
Let's examine another former Cowboys starting running back: Julius Jones.
Jones missed 11 games in a four-year career with the Cowboys, including eight his rookie season. He missed 11 games the first two years of his career and none thereafter.
The Cowboys need Murray on the field, and his absence from the first day of the organized team activities on Tuesday raised some concerns about his long-term health.
It's part of the reason why the Cowboys drafted Joseph Randle in the fifth round. You need quality backups, at least someone who can start in case the starter goes down with an injury.
Murray is a good running back, has the right attitude about the position, is physical, tough and fast. Health is the biggest problem for him at this stage of his career.
Should it worry the Cowboys?
