NFL Changes Could Make Football Safer And More Difficult

NFL Changes Could Make Football Safer And More Difficult
The NFL approved seven changes Tuesday, including the ban of all "chop" style blocks and an expanded penalty for horse-collar tackles.

The NFL announced Tuesday it approved seven proposed changes for the upcoming season, some of which will make the game a little safer and a little more difficult. 

The change getting the most attention is probably the elimination of the chop block. It's a blocking technique when one offensive player blocks a defender above the waist, while another goes low at their legs. It was already illegal in some scenarios; now, the practice is totally outlawed. It looks kind of like this. 

Another change clearly meant for player safety is the expanded horse-collar tackle rule. Under the new rule, a player can be penalized for pulling another player down by grabbing his jersey at the nameplate or above the nameplate — not just inside the collar of the shoulder pads, like before.

In 2015, the NFL tested out moving the line of scrimmage on points after touchdowns — or PATs — to the defense's 15-yard line. That resulted in the lowest number of conversions and most missed extra points in years. The NFL decided Tuesday to enact that rule permanently. 

The NFL also approved a delay-of-game penalty for calling a timeout when you don't have one and three other changes. 

There's still one mystery the league didn't address that's sure to cause some frustrating plays this upcoming season: We still don't know what the NFL deems a catch.
