Point producers , except for the McDavid's, Matthew's, Marner's are by definition streaky goal scorers. Naz is the poster boy for streaky players, 7 goals in a 9 game stretch and then 1 goal for the rest of the season. He did something similar last year where he didn't do jack on the score sheet then went red hot.
Recently I've noticed 2 things about Naz 1) he is getting a boat load of grade A chances, usually means he is about to break out and 2) He is taking too direct of a route to the net, he needs to change his angle just before he shoots, to get the goalie moving or he needs to crash the net just a little more.
If he gets 20 this year I'd say that's a good season for a match up center.
