The Dallas Cowboys are one of the teams that should benefit most in 2013 from the return of injured players, including starting running back DeMarco Murray. Then again, Murray actually has to return.
Brandt: Cowboys will win NFC East
Gil Brandt lists 10 reasons to think Tony Romo and the Dallas Cowboys will dramatically improve their fortunes in 2013. **More ...**
ESPNDallas.com reported Tuesday that the third-year pro will miss at least part of organized team activities this week with a hamstring injury. Last week, Cowboys coach Jason Garrett called the injury "minor." (Murray also sat out those sessions.)
We tend to avoid reporting on muscle pulls in May. But Murray has lost the benefit of the doubt after missing nine total games and countless practices during the last few years. Even when he was healthy enough to suit up, Murray often was missing practices and battling injuries.
Durability is a skill at running back. Murray hasn't shown he possesses that skill, and his style of running doesn't exactly help his chances. The Cowboys have very little depth behind Murray, so they have to be at least somewhat concerned when he can't even get on to the field during non-padded practice season.
