Steelers have had LOT's of injuries but still in it to the end.
Packers had LOT's of injuries to WRs, D, Oline; but as long as Rogers was playing, they still won. Star QB goes down, so does the Packers.
The Seahawks weathered an insane amount of injuries, even a bad oline, until there was just one injury too many. Even then, they remained very competitive. But if Wilson were gone? Not sure they'd win a game.
It's only that the Pats did it best.
Calling 20 years of success despite turnover and injuries an anomaly is an oxymoron. One season; that's an anomaly. 2 decades: that's a plan.
