The New York Giants had the 32nd ranked offensive line in pass-blocking efficiency in 2020 (PFF), and yet they still found a way to make their OL worse this off-season. By cutting veteran right guard Kevin Zeitler, not only did they lose their best lineman, but they created a massive hole at a position of strength.
It seems as if the Giants feel confident that Andrew Thomas can hold down the left tackle spot, Will Hernandez will likely start at left guard, Nick Gates at center, and a combination of Nate Solder and Matt Peart at right tackle.
