The NFL Competition Committee looks at tweaking rules every offseason. The most recent example being the new kickoff rules. This offseason the committee is looking at the Tush Push. The Green Bay Packers were the team that suggested the play be banned. There are rumors floating around there might be enough votes to get the rule change passed. It will be the topic of choice until the NFL draft comes up at the end of April.
In theory, there’s nothing wrong with being stronger than the team across from you. From a pure competition standpoint, it’s ridiculous to ban the play.
