That designation might seem odd when you consider the relative youth of the Lions' primary players. You also might not be interested in a ranking where the full range of age differences is only a few years. In sifting through the Lions' roster, however, the culprit -- if you consider an "old" roster a bad thing -- is a big group of veteran backups.
By my count, the Lions have nine projected reserve players whose ages range between 30 and 33 years old. Six are newcomers to the roster and three -- defensive tackle Justin Bannan, linebacker Rocky McIntosh and defensive back Rashean Mathis -- were signed two weeks ago.
On the one hand, it makes sense to have veteran backups when you have some young starters. If right guard Larry Warford struggles, the Lions could replace him with Dylan Gandy (31) or even Leroy Harris (29). If Darius Slay needs more seasoning, the Lions could replace him with Mathis (33).
McIntosh (30) is available to spell any of the Lions' three starting linebackers. Israel Idonije (33) will back up rookie defensive end Ziggy Ansah, while Bannan (34) and C.J. Mosley (30) will provide depth for Ndamukong Suh and Nick Fairley.
On the other hand, we discussed earlier the Lions' draft issues in the past five years. One of the reasons they needed veteran depth is the inability to develop it on their own. Signing veteran backups also makes it difficult to plan long-term and orderly transitions at certain positions.
Regardless, the team the Lions have on the field at any given point will be a nice blend of young and middle-aged players. If you look at their starters on offense, defense and special teams, you really only see five who are 30 and older. Three of those are on special teams -- place-kicker David Akers (38), long-snapper Don Muhlbach (32) and returner Micheal Spurlock (30).
So I'm not sure there is reason to panic here. But if nothing else, now you know why the Lions rank atop Sando's age rankings.
