Diggs might have found his place in Seattle as the free safety playing off of Jamal Adams and wasn’t terrible in Detroit. But there is an easy argument to make that Diggs had the best season of his career in 2020 and one should expect a regression from that.
In 2020, Diggs made his first Pro Bowl and had a career high in interceptions with 5. Diggs also had his second-best season with tackles (64) and his best with passes defended (10). Maybe, and only just maybe, Diggs is a better player because he is next to Adams and that Diggs moved to free safety from strong safety after being traded to the Seahawks in 2019.
Even with those career-high numbers, Diggs was only the 52nd-highest-graded safety per Pro Football Focus last year. He was slightly better graded than Adams, actually, but then Adams was battling through injuries for a lot of the season and was likely not at his best. Diggs appeared to be mostly healthy.
Of Diggs’ 10 passes defended, 5 came against quarterbacks who weren’t very good. Diggs had 3 in two games against the Cardinals. But against teams with good quarterbacks, like the Cowboys, Bills and Vikings, Diggs had no pass breakups. Diggs could be in for a season where he is not as good overall as he was in 2020.
