Here's the thing though. McVay & Shanny both had defenses playing out of their minds during their SB runs. They also had talent EVERYWHERE & really had no holes on their respective teams. Their weakness was the same though: Qb's who weren't quite as good as the talent around them made them look. This year, McVay didn't have that great defense, His o-line was suspect & his all-world rb was average...9-7 missed the playoffs.
Contrast that with BoB..whose always had to attempt to make it happen with glaring holes on his teams.
Lost 2015 WildCard by 30.........................terrible qb
Lost 2016 Divisional round by 18...............terrible qb, suspect o-line
Lost 2018 WildCard by 14......................... o-line still terrible, suspect secondary
Lost 2019 Divisional round by 20...............no pass rush, suspect..err terrible secondary.
& its funny b/c without the aggressive moves made in FA by BoB & the collective this year, the o-line still might have been on here as a glaring hole.
