I just came across this thread, I am glad I did although it's almost the end of the playoffs.

I am a big fan of the KC Chiefs, but as much as I like them, I have to side with the Bills in this game.Allen and Diggs have been tremendous this year, while we are still not 100% sure if Mahomes will clear the concussion protocol, even if he does, no one is sure how fit will he be, if he isn't at his best or he doesn't play then I don't see how the Chiefs could win it.
If Mahomes is ready, the game should be much closer but I would still lean on the Bills.

As for the GB Packers vs TB Bucs, I think it could go either way. The over/under is at 51 atm and I feel comfortable taking the over as I expect a lot of production from both Brady and Rodgers.

Good Luck!
