Every time the NFL changes a rule, debate ensues and there is almost always never the same interpretation of it.
That said, out of all the rule changes the league has made in the past few years, the new helmet contact rule for 2018 just might be the craziest of them all.
Simply put, no player can strike another player anywhere on the body in a way that contact was initiated with the helmet.
In the high speed world of the NFL, this potentially could create all sorts of issues. The game moves so fast that officials may need to make snap judgement calls on some plays and those could easily affect the outcome of a game.
