The Lions have high hopes for two young interior offensive linemen, but little track record to go on. Bill Nagy, who spent last year on injured reserve, and Rodney Austin, who spent the season on the practice squad, both figure into the Lions' offensive line mix for next season, though where they play remains to be seen. Nagy played four games as a rookie with Dallas, but ankle injuries ended his last two seasons. The Lions claimed him off waivers from the Cowboys last August with an eye toward the future. He could compete for a starting job at center with Dominic Raiola or at right guard after Stephen Peterman's release. "We think he's a really good player, the question is his health," general manager Martin Mayhew said at the combine. "He's sort of in the same situation as Jason Fox where you've got a good player there, and he's put good tape out and we like what we've seen from him. But can we get it consistently? And can he be a guy that can be on the field for 16 games?" With Austin the question is, how big a role is he ready for?
