ESPN Dallas considers Cowboys DT Nick Hayden the favorite to start next to Henry Melton.
Melton will start at three-technique, while Hayden, Terrell McClain, Tyrone Crawford, and Ken Bishop compete for snaps next to him. Hayden started all 16 games last season, playing 843 snaps, but received extremely poor marks both as a run defender and pass rusher at PFF, grading out as their 68th defensive tackle out of 69 qualifiers. McClain will be given every opportunity to win the job.
