Looking at the article the big things that pop out for me in the adv. stats are the giveaway/takeaway, FO% and expected goals for %. When you want to look past purely point totals and such, I'd say those 3 things are about as important of stats as you can get when it comes to affecting the whole flow of the game. Dutch has a huge advantage in GA/TA and sizeable lead in FO%, which means he's able to get his team possession of the puck. If you had two players in equal playing fields, the one who has the puck more is going to outscore the other. I'd guess then that if Duchene keeps those stats going to Ottawa, replacing Turris, he's likely to outscore him, simply by virtue of getting his team the puck more often.
