The New England Patriots unofficially are a quarter way through their season.
Here are the five biggest concerns with the Patriots 1-3 after four weeks:
Offensive line
There's no bigger issue plaguing the Patriots than their offensive line, specifically pass protection. The struggles are well-documented. New England has given up 17 sacks in four games and more pressures than any team in the NFL. It's a coin flip whether or not starting quarterback Jacoby Brissett will be pressured. What makes this even worse, though, is there's no end in sight with 14 weeks left in the season.
