The New England Patriots' interior offensive line was a question mark heading into the 2015 season. Last year's starting guards Dan Connolly and Ryan Wendell were retired and injured, respectively, while the team invested two high draft picks in guards Tre' Jackson and Shaq Mason. Only one position seemed in safe hands: the center spot.
However, according to ESPN's Mike Reiss, it won't be for the first eight weeks of the season:
