Sure, lets just sacrifice all the defence for offence. Lets go score 9 goals a game, but let in 15

Zajac helps us NOT do that. He lets us score. He creates offence through defence. 

That season Zajac got 60 points? Parise scored 45 goals. Zajac got 67 points? Parise scored 38. Zajac never got more than 25. Do you know why you insufferable douchebag? because he played proper defence, and he did his job. He played the anchor and let Parise and Langebrunner go nuts in the offensive zone, while zajac covered them in the defensive zone. You know why he did so well?
