Understandably, most New England Patriots fans will focus their attention on the defense during training camp. It's the side of the ball where the Pats lost four starters, after all, including 60 percent of their nickel package secondary personnel.
But while the offense's continuity won't generate as many headlines (setting aside the Tom Brady saga, of course), one prominent hole does exist in the starting lineup. Though the Pats may have spackled together an interior offensive line last season capable of avoiding self-destruction, that does not mean they have found an adequate replacement for former All-Pro left guard Logan Mankins.
