People keep talking about Mahomes. To me it's more Andy Reid. Now I know Reid didn't win a SB before Mahomes but he nearly won one with Donovan ***** McNabb and also went to about a 1000 championship games.
IMO that team will be favorites every year until Reid retires. The way he makes adjustments with whatever offensive personnel is at his disposal is just incredible (and look at how Mahomes was playing before those changes kicked in - he was forcing balls, trying to do too much, basically trying to play like Allen but wasn't as good at doing that).
Reid uses his pieces on offense the same way Belichick used whatever pieces he was dealt with on defense. The Pats often started badly but as his changes took root they'd gradually round into form.
There's rumours that Reid will retire if they win this SB, I'm not convinced but if he does I can honestly say I'm no longer fearful of KC. They'll always be good with Mahomes but once Reid is gone they stop being scary
