The Green Bay Packers will enter free agency next month with a good chunk of available cap space and several positions of potential need, creating the possibility GM Brian Gutekunst will be aggressive in patching the holes by spending money on veteran free agents.

Over the next month, we’ll go position by position previewing free agency for Gutekunst and the Packers.

Up next is the interior of the offensive line:

Under contract

Lane Taylor (29 years old, signed through 2020)

Corey Linsley (27 years old, signed through 2020)

Cole Madison (24 years old, signed through 2021)

Nico Siragusa (22 years old, signed through 2019)

Anthony Coyle (24 years old, signed through 2019)

Cap hits in 2019

Taylor: $5,443,750 ($2,500,00 dead cap)

Linsley: $8,150,000 ($4,000,000 dead cap)

Madison: $651,082 ($243,249 dead cap)

Siragusa: $570,000 ($0 dead cap)

Coyle: $495,000 ($0 dead cap)

Free agents

Byron Bell (UFA): Signed in late May to a one-year deal. Took over as the starter at right guard late in September and made nine starts, with mostly disastrous results. Struggled in pass pro and provided nothing in the run game. Graded out as one of the worst guards in the NFL by Pro Football Focus. Turned 30 in January.

Lucas Patrick (ERFA): Started six games the last two seasons. Tough, gritty player. Played well during several games to finish the year but hasn’t been consistent. Doesn’t turn 26 until July. Quality backup, if nothing else.

Justin McCray (ERFA): Came out of nowhere in 2017 and found a home in Green Bay as a swiss army knife along the offensive line. Won a job at right guard to start the season but got injured and lost the job to Bell. Ended up starting five games. Limited, but improved in 2018 and has value as a backup at several positions.

Adam Pankey (ERFA): Promoted from the practice squad to the active roster in December. Undrafted free agent has played two games the last two seasons. Experience at tackle and guard.

Need

Major need. Taylor had offseason ankle surgery and labored through a disappointing season at left guard, while neither Bell nor McCray was good enough at any point at right guard. Linsley was rock solid at center, producing what should have been a Pro Bowl season. But the Packers need at least one new starter at guard. McCray and Patrick require legitimate competition, Madison may never play in the NFL and Siragusa is an unknown. Adding an above average starter at right guard could transform the offensive line. Quarterback Aaron Rodgers faced interior pressure far too often last season.

Possible free agent options

Mike Person: Played 1,000 snaps at right guard for Kyle Shanahan and the 49ers last season. Can also play center. Quality pass protector. Worked with new Packers offensive line coach Adam Stenavich and knows the scheme. Was also in Atlanta with LaFleur in 2015.

Rodger Saffold: Will likely be one of the most coveted interior linemen in free agency. Turns 31 in June but has developed into a solid, reliable guard. Played one season under Matt LaFleur in 2017. Too expensive?

Quinton Spain: Experienced left guard who is still only 27 and has played for LaFleur, starting 15 games up front for the Titans last season. Isn’t dominant in any one area but proved to be a reliable pass blocker in Tennessee.

Jamon Brown: Former third-round pick started all 16 games at right guard while LaFleur was the offensive coordinator in Los Angeles in 2017. Went on to start eight games in New York last season. Has 38 career starts. Definitely more comfortable run blocking.

Kevin Pamphile: Started games at offensive tackle for LaFleur in Tennessee last season but has more experience inside at guard. Can play any spot along the offensive line. Versatility could make him a potential backup candidate.
