The New England Patriots offensive line was atrocious in 2015, but there's some hope for the future- the unit was one of the youngest in football.
Youth on the offensive line was the goal for 2015, although probably not to the extent of reality. The 2014 Patriots drafted Bryan Stork to be the center of the future, and the 2015 Patriots wanted to move on from the now-retired guard Dan Connolly and the aging Ryan Wendell.
It seems likely that the 2016 Patriots would have wanted to find a future replacement for aging right tackle Sebastian Vollmer, but the loss of a first round pick makes that slightly more difficult.
