5 underrated free agents the Minnesota Vikings should sign
By Adam Carlson
Mark Glowinski, guard
Odds are that the casual football fan has never heard for Mark Glowinski, but they should start paying attention to him. He’s already played for two teams in his four-year career, but he seems to be coming into his own as an interior lineman.
A former fourth-round pick of the Seahawks in 2015 who lost his starting job to Oday Aboushi, Glowinski has found a role with the Indianapolis Colts after being claimed on waivers, where he is their starting right guard on a line that has done a great job protecting Andrew Luck.
Glowinski had a cap hit of $1,219,000 in 2018 on his rookie deal according to Spotrac, but he is scheduled to become an unrestricted free agent in 2019 and his rise among the NFL’s best guards might be going unnoticed.
In fact, he ranked as the 10th best-rated guard in the league by Pro Football Focus, earning an overall grade of 72.3 for the season (72.0 in pass blocking and 68.9 in run blocking). His overall grade would have made him the second best offensive lineman for the Vikings in 2018, behind only Riley Reiff.
