The NFL regular season currently consists of 17 games, and at this point, it seems like it's only a matter of time before the schedule is expanded to 18 games. NFL commissioner Roger Goodell has been very open about the fact that he would like to see the league implement an 18-game schedule at some point in the near future.

Take it from Chiefs quarterback Patrick Mahomes, a playoff regular since entering the NFL, every additional game takes a physical toll.
