#15 – Tennessee Titans OG Josh Kline

The G-Men will have to spend big money to re-sign Pugh in free agency, and Gettleman also faces a tough decision with guard John Jerry due to his opt-out clause. Jerry, 31, was arguably New York’s most consistent offensive lineman in 2017, starting all 16 games for a second consecutive season.
It’s no secret changes are coming to Big Blue’s offensive line this offseason, but the free agent market is not expected to be stacked with talented offensive linemen. Kline will likely be considered one of the top free agent guards to hit the market after starting 32 games over the past two seasons in Tennessee.
The Titans claimed the 6-foot-5, 300-pound veteran off waivers after starting 13 games for the Patriots in 2015. Kline, 28, has improved his play over the past two seasons and could be a potential replacement for Pugh or Jerry if needed.
#14 – Tennessee Titans LB Avery Williamson

Williamson has started in 61 games since entering the league as a fifth-round pick in 2014. The 6-foot-1, 246-pound linebacker is coming off another productive season, recording 92 tackles, three sacks, two forced fumbles, and four tackles for a loss.
Williamson, 25, would bring some much-needed stability to Big Blue’s linebacking corps. The Giants started seven different linebackers throughout the 2017 season, and the position group is clearly the franchise’s most glaring hole on the defensive side of the ball.
#13 – Baltimore Ravens C Ryan Jensen

Jensen was impressive in his first full season as Baltimore’s starting center. The 6-foot-4, 319-pound center will be a priority for the Ravens this offseason, but it sounds as though he is ready to test free agency, via Baltimore’s team website.
"“It’s been an awesome five years and I hope to be back here, but I’m going to see where life takes me. I’m going to go with the ebbs and flows of life.”"
The former sixth-round pick out Colorado State-Pueblo graded out as a top 10 center in 2017, according to Pro Football Focus. The Giants may need to find a replacement for Richburg, but Jensen could potentially cost more in free agency given his breakout season.
