The story of the 2025 Pittsburgh Steelers has been about surprising contributions from players that were universally viewed as afterthoughts for the majority of their careers. The emergence of guys like running back Kenneth Gainwell and cornerback James Pierre are the best examples of this phenomenon. But another name has quickly risen to the forefront, and that’s Dylan Cook, an undrafted free agent from the 2022 cycle who at one point this season was sitting fourth-string on this team’s depth chart. His ability to hold his own in the starting lineup is a big reason that the offense has played some of its best ball over the past few weeks.
Cook’s long-awaited debut as a starter came in primetime against the Miami Dolphins, a contest in which he was lockdown in pass protection against fairly well-regarded pass rushers in two-time Pro Bowler Bradley Chubb and 2024 first-round pick Chop Robinson. On display was refined hand usage and the ability to anchor down on contact. Maybe the most surprising part was that the coaching staff trusted him enough to avoid sending significant help beyond the Steelers’ base offensive-line-friendly scheme.
Last Sunday’s victory in Motown was the group’s best performance of the season, dominating time of possession and scoring 29 points in the process, while accumulating a season-high 481 total yards. Cook’s showing in pass pro settings wasn’t quite as clean, as he was charged with allowing four pressures on the afternoon and was deserving of partial responsibility for one sack off the edge. However, he made quite the impact in the run game, helping spring multiple explosive plays by getting to the second level to wipe out linebackers.
Nothing gets me more jazzed up than some windback counter.

His next test will be his toughest, with Myles Garrett, the consensus Defensive Player of the Year, on deck. In the first matchup between these two teams, offensive coordinator Arthur Smith had a brilliant game plan to essentially cut the field in half away from the Browns’ best player, a tactic other minds have copied since. Still, there will be at least a few times where he’s going to be put in difficult assignments, and those reps will be where we learn the most about Cook’s progress and shine a light on his potential moving forward. Not to state the obvious, but Garrett would surely love nothing better than to spoil the Steelers’ postseason push and simultaneously break the all-time sack record in front of the home crowd.
Offensive line depth is an oxymoron in the NFL because we simply have fewer 6-foot-5, 300-plus-pound blockers than we do athletic freaks that opt to harass quarterbacks for a living. This explains why we see so many large, athletic human beings...
