There will also be a change with regard to onside kicks that provides greater protection on the kickoff reception, Shaw noted.
“Now, if a kicker drives the ball straight into the ground, one hop, the receiving team is afforded the protection to catch that hop just like it was an airborne kick. They will not be allowed to make contact; that will be kick-catch interference. That will take the one-hop kick out of the game as far as onside kicks. That will be a note to watch as we go through the season.”
This will make end of the game onside kicks when everyone knows it is coming almost impossible. This eliminates the high bounce and go get the ball kick.
I don't think kickoffs from the 35 and touchbacks to the 25 will make much difference.
