I'm comparing him to two of the best for illustrative purposes (although both Toews and Bergeron had very impressive offensive moments as well). The bottom line is that he's a solid 200 foot guy, and that's going to affect his offensive stats. He's not Guy Carbonneau, but he's also not a cherry picker who's going to rack up more points instead of guarding a forward ten feet from his goalie.
So my main point was that when it comes to contact, you can't base it on points alone with him. I certainly expect him to be closer to a point per game player, and even exceed that, as he develops and as his linemates stop hitting posts (insert laughter here).
