The page that's linked has teams ordered by number of solo tackles in the season, even though the search field comes up with text asking which team had the most missed tackles.
Think about the numbers. The top teams are over 800, and the bottom team is the Raiders at 711. If that were missed tackles, then the team missing the fewest tackles in the season would have missed nearly 42 tackles per game. For comparison, the Seahawks had a total 30 missed tackles in the first two games of 2022, which included the disaster against the Gold Diggers in Santa Clara.
What the linked page tells us is not that the Seahawks were the third-worst team at tackling in 2022, but that the Seahawks defense had the third-highest number of solo tackles in the season.
And even if the list had actually contained the count of missed tackles for each team, that wouldn't have really told us which teams were the worst at tackling. If a team's offense is not staying on the field, then the defense will be on the field more and therefore have more opportunities to miss tackles.
To know which team tackled worst, we'd need a rate stat, not a counting stat. Something like missed tackles divided by tackle attempts (tackles plus missed tackles) or missed tackles divided by total plays on which a tackle could have been attempted - either total defensive snaps or total defensive snaps plus kickoffs plus punts plus free kicks plus offensive turnovers. In any case, not a counting stat, but a rate stat obtained by dividing some counting stat by some other counting stat.
