The Chiefs (9-6) have now lost five of eight and will likely have to play their first road playoff game with Mahomes if they even survived the wild-card round. An offense that has sputtered throughout the season couldn't do much against the Raiders and was unable to overcome the costly mistakes. I thought defense played a good game, just two mistakes that gave them two touchdowns there when you're backed up in their red zone so you just can't do that,” Mahomes said.
