20. Brian O’Neil
While the interior of the Vikings o-line was in shambles most of the year, and the LT position was in flux until Darrisaw recovered from injury, O’Neil brought consistency week in and week out to the RT spot and was one of the best tackles in the league all season, especially in pass pro. He finished 7th among tackles in PA% and only allowed one sack all season. He was only average in the run game, which is why he’s not ranked higher.
19. Keven Zeitler
The AFC guard group was right behind the NFC tackles in terms of pro-bowl caliber players and not having enough spots to recognize everyone who deserved it. Zeitler was one of the best players in the league in 2021. He finished top 10 in run-block and pass-block win rate among guards and was 2nd in PA% at the position. He was the glue that held together an offensive line that was hurt early due to Ronnie Stanley missing mostly the entire year and Alejandro Villanueva being a turnstile in his place.
18. Rashawn Slater
Slater was another player that could’ve been in the offensive rookie of the year conversation if o-linemen were considered. He and Humphrey both played at an extremely high level by rookie standards. Slater ended up being the top tackle in the AFC and was rewarded with a 2nd team all-pro and pro-bowl selection. He was also top 10 among tackles with over 500 snaps in PA%.
17. Jordan Mailata
Jordan Mailata has come a long way in a short period of time for a guy who came into the NFL from Australia with only a rugby background and no tackle football experience. He is still learning as a pass blocker yet he was still one of the better tackles in pass pro this season with a 4.34 PA% that ranked top 20 among tackles with 500 or more snaps. And that’s the area of his game he needs to improve. As a run-blocker, he has a case for 2nd best run-blocking tackle behind Trent Williams. There are other guys who are more consistent technique wise such as Orlando Brown and Braden Smith, but he can deliver those splash run block plays that make you say oooohhhh in a way that few others can. He wasn’t able to make the pro-bowl due to a loaded tackle field in the NFC. However, he was in the conversation for the top-five tackles in the NFL in 2021. I rank him sixth-best.
16. Jason Kelce
Jason Kelce is undersized and old, two things that should be working against him at this point in his career. However, he continues to do two things at an elite level. Run-block and not miss games. 2021 marks the seventh straight season Kelce started every game, which is highly impressive at such a high contact position like center. But he’s not just out, there he’s still delivering at a high level. He’s at his best in the run game, where he finished top-five in run block win rate among centers and was named to the OLS all run-block team.
