1. OT Jason Peters
This one is a little more outside the box, and many Giants fans hate Jason Peters, but he would be a much-needed addition to the offensive line room. Peters is currently a member of the Seahawks practice squad, but the Giants could sign him off their practice squad and onto Big Blue's 53-man active roster.
Peters signed with Buffalo as an undrafted free agent in 2004. Yes, 2004 - the same year Eli Manning was drafted. He was a Philadelphia Eagle from 2009 to 2020 and had countless battles with the Giants. His pedigree is unmatched. He is a Super Bowl champion, two-time first-team All-Pro, four-time second-team All-Pro, nine-time Pro Bowler, and an NFL 2010s All-Decade Team member.
Peters is 41, so obviously, he isn't still playing at a super high level, but he did post a starter-quality PFF grade in 2022 playing for the Dallas Cowboys despite playing three different positions (left guard, left tackle, and right tackle).
Peters would provide immense value to New York, even without taking a snap. Giants offensive line coach Bobby Johnson has not been good, but Brian Daboll has no interest in making an in-season change. Peters would bring veteran leadership to the offensive line room and could teach Thomas, Evan Neal, and Josh Ezeudu more about playing the tackle position than Johnson can. Peters would provide an upgrade over Matt Peart and Ezeudu and could put his arm around Neal and show him how to be a pro in a big media market like New York.
