In my opinion, this can only help the Colts Special Teams.  By adding 5 yards to the kickoff, McAfee will easily send much more kickoffs in to the endzone.  With no forms of the wedge block legal, and starting position pushed to the 25-yard line for a touchback, the returner is more likely to stay in the end zone.  It can also help the return game.  I'd be happy with a starting position at the 25.  The league is doing this to cut down on injuries suffered in the return game.  The only negative is, less excitment on kickoffs, but when most of that excitment is experienced from the Colts opponent, I say forget the excitment and let's start at the 25!
