I may be in the minority on this but I think they hit the nail on the head with these rules. This will make kick returns more exciting. I think this will make for longer returns (If it's not a touchback). With no running start I really think it gives the return team a clear advantage.
The only thing that concerns me is the no blocking zone. What happens on, on side kicks? I think this will essentially eliminate any chance at recovering an onside kick. If I'm on the return team just take 1 step forward and the kicking team can't touch you?
I agree. They will have to address the onside kicks but everything else seems like a reasonable approach if they want to keep kickoffs as part of the game. Also, it was developed with a combination of all time special teams players (like Steve Tasker), special teams coaches and trainers. Concussions occur five times more on kickoffs than on any other football play, so input from these guys was pretty comprehensive, I'm sure.
Let's see how it goes. Outline it in pencil and be prepared to erase as it evolves.
