Kansas City Chiefs quarterback Patrick Mahomes has been the center of attention heading into Sunday's AFC championship game showdown with the Buffalo Bills not only because of his level of play and his chase for NFL history, but also because some of the calls he has gotten from refs in big playoff games.

The NFL is preparing to address quarterback slide plays with a new rule aimed at eliminating controversial calls, following criticism of Patrick Mahomes’ tactics during the Chiefs’ playoff run.
