The Giants are signing Faalele to a one-year contract, The Post confirmed, and will add the 6-foot-8 former fourth-round pick into a right guard mix that includes Evan Neal, Joshua Ezeudu and Lucas Patrick.

Faalele might actually have the edge given that he started the final 34 games of Harbaugh’s tenure with the Ravens. He became a lightning rod for disgruntled fans whose anger only grew each time Harbaugh defended his play.

Sounds a lot like Neal’s tenure in New York, though Neal was a first-round pick whose lack of durability became a problem. Neither Neal nor Ezeudu played a single game last season.

“He’s going to start for [the] Giants,” one NFL talent evaluator told The Post. “He can look really bad on a play when he is beaten, but play to play, he’s fine.”

Faalele was ranked the No. 52 guard (out of 79) in the NFL by Pro Football Focus last season. He allowed five sacks and committed eight penalties over the past two seasons combined.

The Giants and Faalele were in talks from the first few days of free agency, The Post previously reported, but waited to see how the market played out.

The recent signings of Faalele and Patrick (65 career starts) could spell the end of free agent Greg Van Roten’s tenure.

He didn’t miss a snap in two years as a Giants starter.
