The New York Giants promised to fix the offense the day after they relieved former head coach Ben McAdoo of his duties. Weeks later, they hired general manager Dave Gettleman and head coach Pat Shurmur.

One thing both Gettleman and Shurmur promised right away was that the Giants would return to focusing on the run game. Working alongside that is Shurmur's heavy reliance on the play-action passing game. In 2017, Shurmur won AP Assistant Coach of the Year by designing and calling the Minnesota Vikings offense. Shurmur turned journeyman quarterback Case Keenum into one of the NFL's most efficient passers.

He did it with a heavy focus on the play-action passing game. According to Pro Football Focus, Keenum finished with the second-highest play-action passing percentage. Eli Manning finished with the 22nd-highest.

However, Shurmur's influence goes far beyond just the usage of the play-action passing game. As we learned in Week 3 of the preseason against the Jets, Shurmur's scheme may have already unlocked the Giants passing game. In one half of football against a strong defensive front, Manning threw for 188 yards passing without Odell Beckham Jr. or Saquon Barkley on the field. Manning threw just six incomplete passes and two of them were clear-cut drops by a wide receiver (Hunter Sharp) who won't play in the regular season -- both drops came on third down and took points off the board.

Shurmur was able to unlock the passing game by mixing up his personnel, formations, and presnap motion. We'll dive into all of that in today's 'Giants Rewatch' focusing on all of the offensive plays of note from the first half of the team's 22-16 win over the Jets.
