Cool, although I don't see a direct connection from that info to the performance of the Cowboys Front-Office-For-Life. Let's try another approach using those same teams, from 2000 through 2020:
Team (playoff appearances), playoff W-L, SB W-L
Steelers (12), 15-10, 2-1
Eagles (11), 13-10, 1-1
Ravens (10), 15-8, 2-0
Giants (8), 10-6, 2-1
Cowboys (7), 2-7, 0-0
Bengals (7), 0-7, 0-0
Commanders (5), 2-5, 0-0
Browns (2), 1-2, 0-0
The Bengals have as many playoff appearances as the Cowboys. The Bengals.
Somehow, two teams in each division have multiple CCG and SB appearances, and at least 1 SB win.
Meanwhile, two teams in each division have losing playoff records and haven't played in a single CCG or SB.
Please explain how this is not a reflection of the Cowboys front office, but simply a product of the Ravens and Steelers playing in an easy division. I'll wait.
