The Giants announced that they have signed linebacker Akeem Ayers and guard John Greco. They also placed linebacker Keenan Robinson (quad) on injured reserve and elevated wide receiver Kalif Raymond from the practice squad. To make room, they cut defensive end Devin Taylor and waived wide receiver Ed Eagan. 
Ayers auditioned for the Giants in September and again on Nov. 8. In the most recent workout, he apparently made a good impression on coaches. Ayers finished out last season with 18 tackles, two sacks, and one interception for the Colts. He graded out as the No. 54 edge defender in the NFL out of 110 qualified players, per Pro Football Focus’ metrics. He didn’t exactly set the world on fire last season, but he does offer experience as a starter from his time with the Titans (2011-2013) and Rams (2015). In 2014, he won a Super Bowl ring with the Patriots.
Greco, 32, joined the Saints in early October but was released without having played a down. Injuries forced him to miss six total games from 2015-16 for the Browns, but he was effective while healthy. Last year, he graded as the league’s No. 18 guard among 75 qualifiers last season, per PFF. All told, Greco offers 111 games — and 70 starts — worth of experience.
The Giants aren’t playing for much at this point, but they are curious to see if Ayers, Greco, and Raymond can be worthwhile players for 2018.
