Think again and see for yourself. Last 30 games and last 17 games of the year when the competition was at its best. This is not no popularity contest cause if it was, you would be right. What they actually do is what counts though so throw popularity out the window.
Kulak's performance when he started the year was different vs the end of the year. Did you ever notice when Petry or Weber are out of position? If Kulak was always out of position, Julien would of not promoted him to play with Petry in the final 30 games of the year.
Do you think you know more than Julien and his coaching staff?
My only concern is can he do what he did in the last 30 games the entire year next year. That's the question we don't know the answer
