It's insane to me that there are actually people, let alone Seahawks fans, who think Earl Thomas won't make the HOF. Almost unquestionably considered the best safety of his era, arguably the best player on an iconic defense, has five All-Pros (3 1st team, 2 2nd team), seven Pro-Bowls, and the All-Decade Team. Yeah, he didn't leave the game on the best terms, but I doubt it costs him more than maybe a ballot or two. Nobody with his resume is getting left out, and he's not losing it just because he got a little weird and alienated teammates at the end. He's in. Easily.
Kam has zero chance. Two second-team All-Pros is nowhere near enough. On PFR's HOF monitor, the average HOF DB is a 98.0. The lowest rating for anyone currently in the HOF strictly as a player (Dick LeBeau is technically the lowest, but his coaching success is a big part of that) is Emmitt Thomas at 52.85, who was a senior nominee 30 years after he last played. He had a successful post-playing career as an assistant too though; I don't know enough to say how much that played into it. Anyway, after him, the next lowest is Ken Riley at 54.85. Chancellor is at 32.33. Notable retired safeties ranked higher include Roy Williams, Antoine Bethea, Bob Sanders, Samari Rolle, Todd Lyght, and Brock Marion. He's not getting in.
Lynch is a borderline case. His stats and accolades lag behind his better contemporaries some, but he'll get in when the voters remember that inductees get to make a speech.
