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. 4 offensive lineman: D.J. Fluker

Position: Tackle

Height/weight: 6-foot-5, 339 pounds

School: Alabama

Why he’s on the radar: The Cowboys are looking for upgrades along the offensive line because of the inconsistent play of starting right tackle Doug Free last year. Getting a rookie with tremendous upside to be either the swing tackle or compete for a starting job should be viewed as a positive for the Cowboys. Fluker is projected as a right tackle and has the size and athletic ability for the position. Coach Jason Garrett respects what Nick Saban has done at Alabama and he'll listen to his evaluation of this prospective first-round pick.

Projection: Late first round, second round

Stretch Truths: The big, strong, physical tackle has 36.75-inch arm length and 10.5-inch hands. ... If he gets those hands on you, it's over. ... Tends to get a little top heavy at times and his balance is inconsistent. My concern is that he is a little heavy-legged. ... Has to play on the right side only as it’s not natural to kick and slide from the left tackle position. ... Overall, I question his smarts to play guard at the next level.
