I think that's a bunch of hogwash (respectively). If the league was on the take, you'd see the Cowboys, the Giants, the Jets, the Rams, Raiders etc. in the super bowls. The NFL is great because the small markets can compete, and by NFL standards, KC is small potatoes.
Now, here's my theory....the Browns and Bengals have got knocked out of the playoffs by the Chiefs recently and so I do expect in this area, people are going to be bitter about Mahomes and the Chiefs. Now, my team - the Titans - have got knocked out by the Chiefs also, but I must be a little more levelheaded when it comes to sports. I don't blame the officials or the league for goodness sake when my team loses. Mahomes is great, Reid is great and the Chiefs have a great thing going. Why is that a bad thing?
Mahomes was a virtual unknown coming out of Texas Tech, no one saw this coming. And yes, Mahomes is black and marketers jumped on the opportunity to market him. Heck, Baker Mayfield markets all kinds of stuff, do you think the Browns got some calls because of it? No.
