Corey Hilliard and LaAdrian Waddle have been splitting first-team reps at right tackle in the Lions' offseason program. Hilliard lost the same battle to Jason Fox last season, but claimed the starting job in Week 2 after Fox went down with a groin injury. Hilliard then suffered a knee injury in Week 7, and couldn't reclaim the gig from Waddle upon returning to full health. Waddle is the favorite to start this season.
