Football has so much randomness nothing is ever a guarantee. Look at that undefeated Patriots team that lost the SB. Greatest team ever but everything went wrong in the SB, all the bounces went against them, and the lesser opponent squeaked it out. This year’s Chiefs team isn’t even a small fraction as good as that Patriots team was, heck they couldn’t even beat a much weaker Patriots team last year at home. Chiefs aren’t even the best team entering this season, the Patriots are the best team probably followed by the Rams. Chiefs are good too though and will be a contender. I’d give them maybe a 7% chance of winning the SB.
