I'm late to the party but here are my observation on some of the rookies in uniform last night.
Vaak: As everyone said, he is ready.
Zboril: Inconsistent, got some great zone exist and first pass with some uh? moment. Could now be a 7th D in the mold of Joe Morrow imho.
Andersson: Will need more viewing of him to make an idea. Looks good when he keep it simple, but not sure he can be good enough defenseively to play in the show as a "keep it simple" guy. Need more time to see what we have there.
Steen: Always arround the play, it seems like it follows him. Great hustle, good skating. Defenitly have a future as a bottom 6 guy. Seeing how much he is invlolve, we might even be lucky and have a "Gallagher" in our hand.
Studnicka: Show great flashes of poise and vision, but too prone to easy give away right now. Could see some time with the Big B's this year if he can protect team puck possession more.
Blidh: Love this guy, he is exactly what we like from our 4th line, sadly I don't see how he could make it with the guy allready in place (Kuraly, Wagner, Nordstrom, Lindholm).
Senyshyn: Same old, while the play seems to follow Steen, Senyshyn seem to skate hard on the ice but never find the play. Hard to critize him, he's trying, but he just can't go where and when he need to go. The end result is a guy uninvolved in the play, but what's frustrating is it's not by a lack of will, he just can't process things at this level.
Lauko: Had a couple of good moment, but kind of lack involvement at times not as bad as Senyshyn, but he seems to think a bit too moch about his positionning right now to play freely.
Frederic: Trying not to make mistake, I'd like for him to try a little bit more with the puck on his stick. He's kinda just taking a space in a jersey right now, not doing any negative or positive impact imho. Personnaly think he as a little bit more in him.
Lindholm: Not a rookie, but I was really impress by his defensive play, great skating, good positionning and hustle. Not sure about his faceoff capacity, he seems to lost some I would have like he won, but didn't take the count.
