The Dolphins’ defense sacked Allen seven times, and the Bills had a total of 107 yards combined between Devin Singletary, James Cook, and Josh Allen. And during the entire regular season, the Bills’ top rusher only had 57 more rushing yards than their quarterback. Sure, Josh Allen is a dual-threat, but he shouldn’t have only 50 fewer yards than their starting running back. Now, there’s no guarantee Devin Singletary returns to the Bills, and if that’s the case, the offensive line is going to need an upgrade. James Cook is a good running back, however, his game isn’t between-the-tackles running. And the expected Buffalo Bills offensive line next season makes that statement even more true.
