I understand that, but I have to point out, KC was doing great things of offense well before Mahomes was QB. Mahomes just made a very good offense great. And it's far different from the Gase offense which was just a dropback offense which, with Manning, succeeded in running standard passing plays. Kansas City has the best QB, possibly the best receiving corps, and until the "incident" had a great running back in Hunt, and yet nobody on that offensive staff does anything less than everything they can do to manufacture plays. There is so much misdirection and pre-snap motion built into their plays that it takes maybe the best cast in the league and makes their job pretty easy, which is why they've been so darn good.
My only thing is...Matt Nagy came from that offensive staff and he's just done a terrible job helping his offense manufacture plays. They spent an entire season last year with an inconsistent QB basically doing nothing but standard dropbacks and not providing a running game all year. It was terrible, and with Andy Reid known to be such a guru who has a genuine love and joy in creating offense, I wonder how much responsibility anyone involved in the offense has actually had. But whoever does their offense does a great job and doesn't just rely on great talent.
