I really believe KC not having Omenihu (DE) for this game will hurt them.
To tell you the truth, I was not impressed with KCs O the last two games. They played against a Bills D# that had a ton of injuries and they scored ZERO pts in the second half last week.
I'm going with SF stepping up on D#, McCaffrey having a huge day and Purdy doing what needs to be done.
Good Luck Guys!!!
