I had heard about the new NFL rule changes that had been proposed for kickoffs. I didn’t understand the benefits of them, but John Mullin from CSN Chicago explains:
Kickoffs, once moved back to the 30-yard line to increase the number of returns, now would be moved to the 35 to cut down on them. Touchbacks would be brought out to the 25-yard line instead of the 20, providing a five-yard incentive to take a knee.
And coverage teams will be limited to a five-yard running start, which might be the biggest change in terms of physics. Force is equal to mass times speed-squared, so if you trim some speed at the front end, you reduce the potential impact at the other end. Throw in a total ban on wedge-blocking of any kind and you have at least theoretically dialed down the chance for injuries on coverage teams, which in fact do suffer more of them than the receiving team.
I guess that makes sense. More touchbacks means that special teams really won’t play a role anymore.
