While the quarterback is usually the one collecting all of the praise or perhaps garnering all of the blame, it's often the battle in the trenches that goes a long way toward determining a team's fate. Winning at the line of scrimmage makes life easier on all aspects of the game and often masks deficiencies at other spots on the roster. Whether it's an offensive line keeping the pocket clean and opening holes in the running game, or a defensive line pressuring the quarterback and slowing opposing rushing attacks, the big guys up front have a massive impact in every game.
After surfing through the league, it's difficult to find teams that are equally efficient on both sides of the ball, so in some cases, it's one side that's carrying the other. There are also cases such as the Philadelphia Eagles, who appeared to be a prime candidate for this list, but their offensive line has been decimated because of injuries.
So which teams are getting the job done in the trenches through five weeks? Here are the top five line-of-scrimmage teams in the NFL, using Pro Football Focus' grades.
What a difference a year and a new scheme has made for the Giants' offensive line. The 2013 Giants were a mess up front as they battled both injuries and ineffective play. QB Eli Manning faced the third-most pressures in the league, and the Giants' offensive line finished second-to-last in Pass Blocking Efficiency as a unit.
Fast forward to 2014 and a new offensive system, and improved play has the Giants' offensive line ranked third in PBE at 87.2 with only 29 pressures surrendered in five games.
