Inside The Pylon noticed that Guge asks his offensive tackles to play with a narrower stance than what Scarnecchia asked, and also had the players operate with their weight leaning forward. While this technique sometimes works with shorter tackles to help engage with pass rushers, it throws taller linemen (like Nate Solder and Sebastian Vollmer) off balance and leaves them susceptible to change-of-direction rushes.
The rest of the offensive line suffered from similar issues as they rose in their stances prior to engaging with the defender. While the Patriots did a good job blocking against stunts, they really struggled to win their one-on-one battles.
