I agree powerplays both 5 on 4 and 5 on 3 need work...but I'm willing to give them a pass for now as there has been very little time to work on them. I should add there were at least 4 posts hit.
I agree on your comments about the K twins (and other Freshmen)...at times you could see potential...but at other times you saw freshmen miscues. Each has size which should help against the more physical teams. Not as quick as Cesana, but good speed once they get moving. Each had some miscues, but it's early.
I'm more confident than you about our 2nd line...but maybe it's false hope as we aren't moving up much (or at all) without a productive 2nd line.
I could add that Apap, Keefer, and Sanford were often paired together and at least two of them will probably be a 3rd checking line. Mattman, Goodsir, and Milan were also often paired and could be a 4th line. Smith, Esteves, Kamer, and Stevens may be the new extra player or move into one of the other lines depending on how the competition goes.
