He got a lot of hype for a couple of really good playoff gameplans - including the second half of that AFCCG when they went to a consistent 3 man rush and frustrated Mahomes.
But this is his 6th year as DC and his defenses have ranked: 28th, 26th, 18th, 16th, 31st and going into this week was 23rd.
And it isn't as though he can claim they are bend but not break, with the exception of 2022 (6th) they have been in the bottom half of the league every year in points allowed too.
That is a THIN resume for HC contention.
