Some may scoff, but I think he plays a game similar to Parise. He has a knack for the net but not a tremendous shot, good skater, not afraid to play the physical game even with his "smaller" size, gives 100% on every shift, plays the whole 200', and has great leadership qualities.
I don't know that he's built to take the beating that Parise is. Otherwise, I can't think of any other player that I'd compare Haula to.
He doesn't have a pure sniper's shot, but it's good. He hustles like crazy. He can make some sneaky passes if the circumstances are right... Yeah, poor man's Parise at center.
