years old when Eli Manning began his NFL career. Manning is entering his 16th season Kerry Wynn Color Rush Jersey , while Lawrence is arriving as a first-round draft pick.Age isn’t always “just a number.”“In the locker room, I feel their age,” Manning said, via Rod Walker of nola.com. “At 8 o’clock at night, I don’t feel their age. I’m ready to go to bed, and they are just getting started rocking and rolling. I can’t hang and do everything they can do off the field. But on the field, I still feel like I can still run with them and they keep me young.”Manning’s best days are behind him, but he’s not done yet.At 38, Manning is the third-oldest quarterback in the league behind only Tom Brady (41) and Drew Brees (40). The Giants quarterback is the fifth-oldest player in the league currently under contract.Manning is coming back for another season to compete with Daniel Jones for the starting job. (Even if Manning doesn’t see it as a competition.)But the end is near for Manning, who concedes that much.“You take it year by year,” Manning said. “I’ve been blessed going into my 16th year. That’s been a blessing in itself. I love what I’m doing. I love the work that goes into it. You never know when it’s going to be your last year or when it’s going to be the end for you, so you try to take advantage of the years you’re here and enjoy every moment.” All eyes — at least those not on the awful officiating we saw during Championship Weekend — are on the 2019 NFL Draft. The Shrine Game just concluded. We are entering Senior Bowl week. Draft buildup is kicking into high gear.Still, NFL free agency comes before the draft. The negotiating window begins March 11 and the actual signing period March 13. Between now and then we will occasionally look at some of the positions the New York Giants might target in free agency and see who could be available.Today Will Hernandez Color Rush Jersey , we look at right tackle. Ereck Flowers began 2018 as the Giants right tackle and was replaced after two games by Chad Wheeler. Pro Football Focus graded Wheeler No. 60 out of 61 qualifying NFL tackles in 2018, and only five tackles gave up more pressures. The Giants have to do better at that spot.Here are some of the players who could reach the market in a few weeks.Jared VeldheerAge: 32 | Experience: 92018 team: Denver Broncos2018 cap number: $6.875 millionPFF grades: Overall (62.4) | Pass (68.4) | Run (60.7)A left tackle when he was drafted by the Oakland Raiders in 2010, Veldheer has transitioned to the right side the past couple of seasons. Veldheer spent four season in Oakland and four with the Arizona Cardinals before joining the Denver Broncos last season.The Denver Post says Veldheer is still a “well-respected veteran.” The problem is he has missed 15 games the past three seasons due to injuries. At this point in his career he might fit better as a veteran swing tackle, if he were willing to accept a backup role.Bobby MassieAge: 29 | Experience: 72018 team: Chicago Bears2018 cap number: $5.1 millionPFF grades: Overall (71.5) | Pass (78.9) | Run (57.2)Massie is coming off the best season of his career, having allowed just one sack and 26 pressures in 683 pass-blocking snaps. Walter Football says “Massie was once considered a liability as a starter on the offensive line, but he has improved each year. He’s become a solid right tackle who pass protects very well.”Ja’Wuan JamesAge: 26 | Experience: 52018 team: Miami Dolphins2018 cap number: $9.341 millionPFF grades: Overall (70.8) | Pass (67.3) | Run (69.1)James is a former first-round pick and if the Dolphins let him reach free agency he figures to have a number of suitors. Walter Football says “Ja’Wuan James is a stellar right tackle, but had a down 2018 season because he played through a knee injury. He’s still young (27 in June), so he should be able to rebound at 100-percent capacity to open the 2019 campaign.”The Palm Beach Post says “James is likely to command top dollar as few 26-year-old tackles with his combination of size and athleticism hit the market. Due to the nature of his one-year deal, James was the highest-paid right tackle in the league this season.”Jordan MillsAge: 28 | Experience: 62018 team: Buffalo Bills2018 cap number: $2.25 millionPFF grades: Overall (56.0) | Pass (66.5) | Run (47.7)A durable player who did not miss a game for the Bills during the past three seasons. Pro Football Focus does not see Mills as a quality starter:Our friends at SB Nation’s Buffalo Rumblings are ready to kick Mills to the curb:Daryl WilliamsAge: 26 | Experience: 42018 team: Carolina Panthers2018 cap number: $2.046 million2017 PFF grades (played only one game in 2018): Overall (78.0) | Pass (78.0) | Run (69.3)Much like Andrew Norwell a year ago, this is the player most figure the Giants will target as they look for offensive line upgrades in free agency. Norwell, a former undrafted free agent, became an All-Pro after being discovered by then-Panthers GM Dave Gettleman. Williams became a starter, and a good one Lorenzo Carter Color Rush Jersey , in Carolina after Gettleman drafted him in the fourth round of the 2015 NFL Draft.He’s headed to free agency, has the Gettleman connection and the Giants have a need at right tackle. Put two and two together, and the Giants pursuing Williams seems obvious.Walter Football says “Williams is Carolina’s best offensive lineman, and he’s only 27 (in August), so he’s still due a large contract despite barely playing last year.” There is that. Williams played in only one game in 2018 after suffering a knee injury that sent him to IR.The Charlotte Observer said recently that Williams is “likely to become a free agent” because there is a “monster gap” between what the Panthers are willing to pay and what Williams is looking for.The top annual salary for a right tackle is the $11.252 million earned by Lane Johnson of the Philadelphia Eagles. Mitchell Schwartz of the Kansas City Chiefs ($6.6 million annually) is No. 10 on the list in terms of right tackle salary.Will the Giants see Williams as a player worthy of being paid in that range?Other names to knowBenjamin Ijalana (New York Jets), Joseph Barksdale (Arizona Cardinals), Andre Smith (Cincinnati Bengals), T.J. Clemmings (Oakland Raiders). Oh, and Ereck Flowers, Bobby Hart and Marshall Newhouse could all be free agents, too.
