Some food for thought: Our pass defense in the two seasons Adams was on the field, ie 2020 and 2021, were ranked 31st. In 2022 with Adams missing all but the first game, we experienced a huge improvement, ranked a very respectable 13th. A coincidence? Obviously, there's a lot of things that go into a total passing yards surrendered stat, but it is a fact that's a little hard to get around if the argument is that he makes our defense better.
2020: Griffin was overrated by so many people.
D.J. Reed was a few years away from realizing his potential
Tre Flowers was Tre Flowers (I have mentioned him, there will be one poster who will rip him shortly since he brought him up even in posts about offense)
Quinton Dunbar was a very poor scheme fit that we never should have signed and he was out of the NFL afterward
Ugo Amadi was decent at best and last season was a healthy scratch for the Titans towards the end of the season
2021: Sidney Jones was an interesting signing. He had not really been a starter before we brought him in and hasn't been a starter since
D.J. Reed, again a year away from getting it
Tre Flowers was Tre Flowers (I have mentioned him, there will be one poster who will rip him shortly since he brought him up even in posts about offense)
Ugo Amadi was decent at best and last season was a healthy scratch for the Titans towards the end of the season
John Reid who was a safety was tried at corner, he was not good
Gavin Heslop is out of the league
Michael Jackson was a year away from getting it
Tre Brown was a very promising rookie that was injured
2022: Tariq Woolen was a total revelation and Pro Bowler as a rookie and should have been rookie of the year
Michael Jackson got it and played fairly well
Tre Brown came back from injury well, but Jackson was the starter
Coby Bryant played very well as a rookie
Apart from the corners being superior in 2022, the truth is that Wagner was a major liability in coverage in 2020 and 2021. The only decent part of Cody Barton was his coverage. It was not something I would say was good, but he was not nearly as much a liability as Wagner was.
We also had a much better pass rush in 2022 than in '20 or '21. Sacks by non-DB's were up by double digits last season over both other years. Seems as though our defense was better because the new players were better than the ones Adams actually got to play with in 2020.
