Seahawks left guard Damien Lewis
I think Lewis is a must-extend player. He was near-Pro Bowl-worthy in 2022 and was graded as the 11th-best guard in the NFL last year, per Pro Football Focus (subscription required). For all of the criticism that the interior of the Seattle offensive line got last season, most of that should be directed at the mess at center and right guard. Lewis at left guard was not the problem.
Lewis is also just 26 years old and can hold down left guard for the next five years. Building cohesion is likely the biggest key to having a successful offensive line, especially if there is talent on the unit. Lewis is a talented player and that has borne out over the last three years, but Lewis got more comfortable and more efficient as the 2022 wore on. The only reason he didn't grade even higher on PFF's scale is that the first four games of last season weren't Lewis's best.
But with the Seahawks having two second-year offensive tackles, and potentially two rookies starting at center and right guard at some point during this year, Lewis would be a veteran presence to help the young guys on the line not just this year but next. A line of LT Charles Cross, LG Lewis, center Olu Oluwatimi, RG Anthony Bradford, and RT Abraham Lucas could be one of the more formidable O-lines in the NFL by 2024.
Lewis is going to deserve a pay hike, though. The top 13 guards in the league all make $10 million or more. Still, Seattle is saving money on the offensive line currently as potentially all the other four starters on the line could be on rookie deals for at least the next three seasons except for Lewis. But extending him simply solidifies a dangerous offensive line for several more years.
