Coaches with two SB/NFL championships - make it make sense please

[saturdaysarebetter]

Coach A: 11 years, 114-62 .648 winning percentage, 10-5 post-season .667 winning percentage, 8 winning seasons, 9 non-losing seasons
Coach B: 15 years, 104-75-9 .581 winning percentage, 3-1 post-season .750 winning percentage, 10 winning seasons, 11 non-losing seasons
Coach C: 12 years, 97-87 .527 winning percentage, 8-3 post-season .727 winning percentage, 6 winning seasons, 7 non-losing seasons
Coach D: 20 years, 170-150 .531 winning percentage, 12-7 post-season .632 winning percentage, 10 winning seasons, 12 non-losing seasons
Coach E: 20 years, 170-138 .552 winning percentage, 8-6 post-season .571 winning percentage, 10 winning seasons, 13 non-losing seasons

Coach C is in the hall of fame.
He had the lowest regular season winning percentage of the five.
He had the lowest number of winning seasons and tied for the lowest rate of winning seasons (50%) of the five.
He had the lowest number of non-losing seasons and the lowest rate of non-losing seasons (58%) of the five.
Coach B had a higher winning percentage, a higher post-season winning percentage, a higher rate of winning seasons and a higher rate of non-losing seasons than Coach C.

Coach A is George Seifert
Coach B is Buddy Parker
Coach C is Tom Flores
Coach D is Tom Coughlin
Coach E is Mike Shanahan

Make it make sense please.

Flores and Dungy have similar arguments as minority head coaches where both played--though Flores first hispanic starting pro QB--were head coaches, again Flores first hispanic HC--and both SB winners with both getting voted in as minority firsts.

Flores also was part of every Oakland/LA SB championship team that helped him get elected. Also one of only four players I believe, who was on an AFL roster during its entire league existence. Like Seifert, he also followed another HOF coach.

We all know Parker should have been elected, but a number of voters circumvented the rules and by-laws of the HOF to keep him from getting his deserved gold jacket. A sham.

frankly since the 2020 Centennial class, the voters have made a complete mess of the coach queue, now only made worse by having them compete directly with seniors and contributors.
