Lions have second-youngest projected starting offensive line in NFL

As noted after this year's NFL Draft, the Detroit Lions' offensive line has been overhauled in the last few years. The Lions went from having one of the oldest O-lines in the NFL to one of the youngest by adding Riley Reiff, Laken Tomlinson, Travis Swanson, Larry Warford and LaAdrian Waddle since 2012. The Tomlinson pick in the first round this year really put them over the top in that regard, and it turns out that the Lions now have the second-youngest projected starting offensive line in the entire league:

How does this compare to past years? Via Jimmy Kempski, here's how the Lions' ranking has evolved since 2012 (the higher the ranking, the older the average age):

2012: 2nd
2013: 16th
2014: 13th
2015: 31st

As you can see, the Lions went from having the second-oldest starting offensive line in 2012 to having the second-youngest in 2015. That's a pretty dramatic overhaul, and the change just from 2014 to 2015 is pretty dramatic as well. I suppose that's bound to happen when you say goodbye to the oldest starting offensive lineman in the league (Dominic Raiola) and another starter in his 30s (Rob Sims), but the numbers are pretty eye-opening either way.
