fahrenheit with a windchill of negative 20. the brutal cold likely contributed to patrick mahomes' helmet cracking. you can see an entire chunk missing from it. >> i'm sure it had to do with it being really cold, but yeah, i didn't know what happened in the moment but i got in the huddle and everybody was tell ming me. we got to talk about where we store the back up because it was like frozen. when i tried to put it on, it was completely frozen. i couldn't get it on. i don't know if anyone got a picture of it, didn't look great, but we were kind of able to adjust it on the sideline and get it rolling from there. >> the chiefs iced out the dolphins in a 26-7 victory and with me now is rachel nichols. rachel, great to see you. i guess in kansas city, they were serving up frozen fish last night, but i have to say, and the chiefs have been sort of all over the place this season.
