The key question is do you believe he only allowed two sacks from 2019-2022? In 2022 we allowed 54 sacks, 3rd highest in the NFL. Is it really plausible that one of the 5 offensive linemen allowed 0 sacks and only one holding penalty in a year like that? If so, he should have really stood out because those around him sucked, right? Granted, his pass blocking has been better than his run blocking during his decline but that doesn't mean he has been stonewalling. He was giving up ground which contributes to there not being a pocket to maneuver, creates gaps for other players to exploit, etc. Also, the manner in which they assign sacks is subjective at best. A G can give up immediate pressure that forces the QB straight into an edge defender who was being blocked exactly as he should have. After games in 2022, were you thinking "Man, Zack just dominated his guys today."? Cause that is what we should be thinking when we see the best player at a position play.
As for other players around the league being more deserving, I'm not sure how much you watch other teams but there are a lot of really good players who don't get the recognition they deserve from the general public. Lindstrom from the Falcons, Zeitler for Lions, Teller for the Browns, etc.. Were their individual efforts recognized in the voting or minimized by their teams record? discounted because they weren't a top 16 pick who was dominant early in their career?
At the end of the day, I wasn't seeing a player that was dominant. And I haven't seen him being dominant in quite a while.
