The reason NFL owners passed a proposal to move kickoffs to the 35-yard line is so there are more touchbacks and less returns going forward. Kick returns are one of the more dangerous plays in football, and the NFL's hope is that less serious injuries will occur since there should be less kick returns.
For the Detroit Lions, we all saw just how dangerous kickoffs can be when Zack Follett hurt his neck covering one last year against the New York Giants. The injury put his playing career in serious jeopardy, although he is signed for next season and will try to play. If he is covering kickoffs next season, there is obviously still a chance of an injury when returns happen, but less returns mean there will be less opportunities to get hurt. Even so, he doesn't sound like a big fan of the changes.
Change to the kickoff rules! HOW BORING! This is coming from the one who got hurt!
I definitely understand the idea behind the change, and the Lions do too, as they voted for the proposal for the reason of player safety. My problem is that it could take kickoffs out of the game quite a bit. Now, in the NFC North, which includes opposing players like Percy Harvin and Devin Hester, that might not be the worst thing in the world. With the Lions finally finding a great kick returner in Stefan Logan last year, however, it sucks that we might see quite a bit less of him in the future.
