I still think the Chiefs are the best team in the AFC. Losing by 3 vs healthy, rested Pats on the road with your two best defensive players hurt, 2 more starters hurt, and 2 OL hurt is not a terrible result.
Berry will be back by the end of the year, and hopefully Houston will be healthy too, +Sorenson, which will shore up linebackers. Maybe trade for Patrick Peterson or an ILB?
And BTW, Mahomes is legit. My prediction would have been right if Chiefs would have gotten that 3rd down stop... oh well.
