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. 2 running back: Joseph Randle

Height/weight: 6-foot-4, 204 pounds

School: Oklahoma State

Why he’s on the radar: With durability issues regarding starter DeMarco Murray, the Cowboys are seeking quality backups in case of injury. Randle isn't the fastest running back in the draft -- posting 40 times of 4.54, 4.60 and 4.63 -- but he's a quality runner and led the Big 12 with 1,417 rushing yards last season. Randle (14 touchdowns in 2012) is a physical runner and can catch passes out of the backfield, making him an option on passing downs.

Projection: Second or third round

Stretch Truths: Is a straight-line back who runs upright and does not show a top-end gear. … Has good hands and runs good backfield routes. … Has adequate punch and pop as a pass blocker. … Because of his upright style, he needs to be in a zone scheme. … Overall opinion: I don't see him as a tough north/south back.
