if that's their offensive line next year, the lions are in a world of hurt.
due to injury (branch/kirby/laporta), age decline (decker/glasgow), off field issues (arnold), and poor draft decisions (rakestraw/manu/vaki), the lions are a bit behind the 8 ball. they are now an expensive team (due to all the great drafting holmes did in his first two years) and need cheap talent to fill in the holes.
injuries and arnold's uncertainty are killing them by turning what was a strength (secondary) into an immediate need. the oline aging everyone saw coming. manu was supposed to help with that but he's been a miss so far. he has this season to figure it out. if they take a swing tackle early, he's a cut candidate.
