Don't get it twisted... The new helmet rule could end up being 10x worst then the catch rule has been. If you have watched any of the first few preseason games this year. There's a lot of judgement call's being made by the refs, and unlike the catch/no catch. You can't have the helmet call reviewed currently, which is very concerning.... If the way these refs are calling the preseason games so far, continues into the regular season. Not even a full two week's of preseason games have been called, and there has been at least a half dozen call's I have seen where the defender hit with his chest/shoulder, and got called for using the helmet. Talk about bad calls, and I'm pretty sure these are 15 yard penalties as well. So that can be critical late in games, and I can only imagine ref's this year deciding the final outcome of games even more. Which will be a major issue all around. Currently I think there's only one thing the refs can review for these types of hits/fouls, and that's to see if there was targeting like they do in college football. If they feel there was, they can eject the player. Which I don't have an issue with that. However teams SHOULD be able to challenge helmet hits, to make sure the call's are right. Especially when the refs are being asked to make split second calls on the field, and depending on the angle they're seeing it happen from. A hit can look better, or worst in live action, so replay is needed, if they want to tone down leading with helmet hits, and make the game better for players, and fans watching. They have to allow reviews of these calls. Because we're talking about only 16 games season deciding if teams make it into the playoffs. Can't have refs making a couple judgement calls that cost a team 1-2 wins, and end up missing the playoffs due to them call's not being able to be reviewed. Because then you have media, and fans only remembering them two bad calls late in the game that cost them a win, and a chance to advance in the post season. As a replay of them call's will show the calls were not right. Ultimately that hurts viewership, and the NFL product overall. Yes the NFL grades the refs, but guess what? The NFL doesn't even have a full time slate of refs for their billion dollar product. So ultimately they're very laid back in the sense of suspending refs for bad games they called. Each week the NFL reviews all these calls, and guess what comes of the bad call's by these refs? The NFL sends a letter to the teams saying we're sorry that was a bad call, it shouldn't of happen. However that "Sorry" doesn't help the outcome of that game. As a fan I wouldn't care as much, if they were playing more games. But 16 games, is a small number of games to decide if they team advances to the playoffs, or not. So the outcome of every game is important, and so call's have to be made sure they're right. EDIT: The last thing I want to mention on this matter. If the NFL is so focused on speeding up the game, with less reviews. When they add new rules, they have to be better on detail's of each rule. The Catch/No catch rule has been a major issue for a good period of time. Now they add the helmet rule, and you have players trying to do right, and hit with there chest/shoulder. Yet they're still being flagged by the refs, because the NFL is giving REFS 100% control on if it was a helmet hit, or not. With no option for teams to have the play reviewed.
