Pats vs Chiefs:
For the Chiefs to win, they'll have to rely on their defense and special teams. With Maclin out (high ankle sprain is usually a month of recovery at the least), they lose a vital piece to their throwing game. Only other real threat is Kelce and like how BB usually does, he'll double him taking him out of the game and stack the box.
...Chiefs will have to get as much pressure on Brady as they can. Front 7 is full of talent and with a banged up Pats oline that's been shaky, they must take full advantage of it and disrupt Tom. Disrupt Tom and you're in it. The running game has taken a bit hit with Blount out and don't have any legiamate threats that can take a handoff and pound it up the middle. The running game has turned into an extension of Tom thus, must disrupt him as often as they can. If they can do this and their special teams can be on their game, Pats have a good shot at losing. If they can't however get to Tom enough, I say the Pats take it.
