Moving the kickoff basically eliminates the return game, one of the most exciting elements of the game. While it will reduce the number of injuries, moving touchbacks up 5 yards isn't going to compensate for the loss of game changing plays.

The more player safety related change is all players on the kickoff team must be within 5 yards of the ball so they aren't getting a 10-15 yard running start before the ball is kicked.
