Giving up a Safety

It will be hard for the NFL to take out the kickoff due to the ensuing possible onside kick at anytime.
They can and have however moved up the Kick off spot to almost ensure that a kickoff will go into the end zone for the returner to take a knee for a touch back or the ball kicked through the end zone for an automatic touch back.

The league changed the rule on safeties a few years ago, moving the line of scrimmage back 10 yards on the ensuing kick, this poster lobbied the league to make changes but apparently 10 yards on the kick was not strong enough a deterrent on coaches to play the game and not give up points that their Defences work hard to prevent!
