This makes absolutely no sense. Every year 1 team wins the Super Bowl. That means 31 teams don't. So you're penalizing them for doing what the odds (and reality) would predict will happen most seasons? At most in a decade only 10 different teams can win a SB. That means at least 22 teams are going away empty handed. With repeat winners I think the total of different SB winners this decade will be what? 7? That leaves 25 teams on the outside looking in.
This doesn't even mention the records (individual and team) that have been broken this decade by the Colts, or breaking barriers with the first black NFL champion head coach. That shouldn't even matter really, because by even your convoluted perception that only playoff success matters the single Super Bowl win puts them in the top 20% of the league alone.
And if the top quarter of the league is getting C's .... I guess we're handing out 20 different grades D's and F's according to your cracked out scale of grading. Apparently we'll give out a single A, a single B and everyone else is stuck at C, D, F.
Hence, why the C is humorous to me. Nobody could possibly be .... off .... enough to truly believe that. Even more so after hearing the logic that didn't even support such an idea. I'm sure if I went into each teams "playoff successes" for the decade, I'd find 28 teams or so with fewer playoff victories this decade. If I had to guess the Patriots and Steelers would be the only 2 I'd expect it from.
This dudes as good as any comedian.
