I actually throttled back PPP recently I think, but I'll have a look. As it stands, special teams players get a bonus point for every PPG or PPA they notch (along with SHG/SHA's I believe).
I'm not entirely sure that's necessary - with only 9 teams in the league last year, there was plenty of talent to go around.
Plus, I've tried to build the stats reward system primarily around things that help the team win - lots of hits or fights don't really do that. Matt Martin, I'm looking at you.
