It's a great change compared to the dogshit system they've been using over the last several years, but that doesn't make it good. It just clears the very low bar we've set for the NFL. Any rule that still involves physical contact is now considered Chuck Bednarik-level badassery. This league is amazing at playing "just the tip" on us, which is why we'll continue to watch even as it evolves into flag football.
Also, Cyberjag is right about returns potentially getting out of hand, especially now that common forms of tackling are being outlawed. People who are loving this are going to start hating it very quickly if it's having an outsized impact on games. Fans and commentators are going to be apoplectic if Raheem Blackshear becomes a more valuable player than Bryce Young (or whichever quarterback the Panthers are using in two years). So, rather than a new kickoff, this feels more like the last stop before outlawing the play altogether.
