Earl has five All-Pros, seven Pro Bowls, was named to the 2010s All-Decade team, and was arguably the best player on an iconic, championship defense. He easily makes the HOF. Being kinda weird late in his career will at worst cost him maybe a ballot or two.
No chance for Kam. He doesn't have the accolades. Also, looking at Pro Football Reference'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 making it.
