The issue I see is his attitude, some say it's his maturity level, others (I for one) think that he believes that he is better than he really is. He expects to be a top line center and will accept nothing less. Hopefully with Murray kicking his ass to the AHL for the season helped humble him a bit and he plays better this call up. I really feel that Murray/Nolan is growing weary of Grigorenko. So much so that I think this is his make or break call up. If he plays bad he will be banished to Rochester until he gets traded.
He should get a nice long look, he better take this opportunity by the balls
