To help preview who might be on the Dallas Cowboys’ board for the NFL draft, ESPNDallas.com has identified five players at five key positions that we’d like to learn more about. Along those lines, we’ve asked former Cowboys assistant coach Glenn “Stretch” Smith – the official scout of Galloway & Company – to study tape of each player and give his thoughts.

No. 1 Running back: Andre Ellington

Height/weight: 5-foot-9, 199 pounds

School: Clemson

Why he’s on the radar: Ellington might not be the best running back in the draft, but he's a good fit for the Cowboys to back up DeMarco Murray. Ellington is elusive, not afraid of contact and produced solid numbers in college. He was one of four running backs to get 1,000 yards in the ACC last season. The Cowboys want their backup running backs to play special teams and that could be a negative for Ellington, who isn't that big. Ellington would be a nice selection to challenge Lance Dunbar as the No. 2 running back on the roster.

Projection: Third or fourth round

Stretch Truths: For his size, this back will attack the line of scrimmage and at the point of attack. ... He shows straight-line speed, but I do not see a top gear. ... Has vision and reads his blocks well. ... Flashes balance and body lean. ... He’s a tough kid who takes big hits, but he’s not a power-after-contact type back or very physical as a pass protector. ... Has some kick return ability.
