5 Cowboys undrafted free agents with best chance of making 53-man roster

3. Earl Bostick Jr., OT, Kansas

A former tight end, Earl Bostick Jr. transitioned to offensive line where he started 25 games at left tackle over the past two seasons for the Jawhawks. An athletic big man, Bostick Jr. has the intriguing movement skills that are worth bringing into a camp to try and develop with NFL coaching. Bostick Jr. only played left tackle in college, but he fits the Cowboys front office profile as a player that they could try to flex at both guard and tackle.

"We typically like to take tackles and move them into guards because tackles are usually your best athletes, that way you have an athletic offensive line. "

- Will McClay, Dallas Cowboys VP

The Cowboys coaching staff is reportedly still a believe in last year's fifth round pick Matt Waletzko's ability as a swing tackle, but behind him the rest of the offensive line depth chart is undecided. Depending on Terrance Steele's recovery timeline, Josh Ball and Asim Richards are the other main competition for swing tackle roles for the start of the season.

If Bostick Jr. can turn some his flashes into consistent play during training camp, and show some tackle/guard flexibility, he has an outside shot of securing a roster spot.
