Colts have 1 of the more vanilla defensive schemes in the league and Mahomes has been excellent vs zone all year. Think unless the weather is a huge problem that KC should be fine.
Yes, the Colts play a huge amount of zone coverage more than other NFL teams. But that also could be an advantage in snowy weather with tipped balls.
I hope they take a cover corner with either their late first or the Jets early 2nd rounder in draft
