To continue our training camp preview series, here are three players who are entering make-or-break camps. These are younger players who, at one point, had relatively intriguing expectations, but now find themselves entering critical periods of their Lions tenures without much on their résumés to show for it.

Glasgow is the biggest offensive line health concern heading into the season. A reliable, solid player for most of his career, his performance dipped last season possibly due to knee injuries. He was listed twice with an unspecified knee last season and missed one game due to it. There was no specific injury seen on video last year.
