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 safety: Tony Jefferson

Height/weight: 5-foot-11, 213 pounds

School: Oklahoma

Why he’s on the radar: The Cowboys are thin at safety thanks to the release of veteran Gerald Sensabaugh. Barry Church is one starter, but there is some concern about who will play alongside him. If the Cowboys don't draft a safety in the first two rounds, maybe getting Jefferson, who can play both safety spots, is an option. He's good in coverage and playing near the line of scrimmage.

Projection: Fifth round

Stretch Truths: Does not have top-end speed (ran the 40 in 4.75 seconds). … Not natural pedaling and turning his hips. … He is a box safety who can play the run with force. He’ll tackle with pop and deliver a blow. … Could be a demon on special teams but lacks size and speed to be an elite safety. … Cowboys need better in the first four rounds.
