Using your stick to "push" another player is literally the definition of a cross check.
There are a few of dark horses in this org that I like & keep an eye on. I've always liked Parker Kelly since I saw him at a development camp with a non-stop motor & for a smaller guy likes to hit & seems similar to Greig or vice-a-versa although I assume Greig should be the better goal scorer.
Guennette is another young guy who is under the radar, good size, good skater & seems to be able to put up pts. Not sure how good he is defensively, but with his size I would guess he doesn't get pushed around much either. He could turn out to be a poor man's Chabot & he's a right shot which probably puts him in direct competition with Thomson & Brannstrom who I don't see playing on the left side on any future team given that it should be Sanderson's spot.
Kastelic is the 3rd dark horse, again after seeing him at the development camp & rookie tournament. I noticed that the coaches were using him a lot on faceoffs in both the offensive & defensive zones in most situations, but especially on important faceoffs. They clearly think he was their best faceoff guy & maybe that's his path to the NHL to be great at faceoffs, we'll see. He's big, tough, not a great skater but not slow either & he hits, block shots & plays a decent defensive game & can chip in offensively. I would characterize this guy as potentially a good playoff warrior. I have high hopes for Kleven as well.
