The NFL's annual meeting will be held in Arizona, where owners, executives, and coaches will discuss various topics including replacement officials, potential rule changes, artificial intelligence, health and safety issues, international growth and flag football. The biggest proposal is to allow the replay center in New York to advise on any missed roughing the passer or intentional grounding penalty, which could have led to an ejection. The NFL's use of replacement officials in the 2012 season resulted in several mistakes and wrong calls, including the "Fail Mary". The league has also proposed minor tweaks to the dynamic kickoff rule entering its third season. The league's goal is to have fewer, lower injury rate on play, which has been accomplished by more large plays and large data.
