Carrie Jersey over the past several seasons, having mi sed at least three games every year since 2016. When healthy, he remains one of the game's top tackles and is an eight-time Pro Bowler, but the "when healthy" qualifier is increasingly nece sary.Dallas is already undergoing ma sive changes along the offensive line this season, with the team having let left guard leave in free agency and then cut ties with right tackle . The former was expected to be replaced by first- Rashard Higgins Jersey round pick , whom the team identified as its left tackle of the future but also someone who could start at guard next to Tyron Smith in the short term.
