I think the individual skills part is the key part. You can see a general improvement of the team cycling the puck- assuming that what we saw against Northern and Ferris was representative- during even strenght play. So with the fowards already getting into the motion thing- the natual movement of the players during the PP picked up a lot. The comfort with the puck, the speed that they pass it, the better knowledge of where others will be- it's all coming together.
Now it's a matter of just better shooting. Or, more correctly, a few players "fixing" their fight with the puck- most noteably Trieas and Moffie. Poor guys are really fighting it right now. Both are clearly making better decisions, both are playing both ends well- but both just seem to be not able to keep the puck at the end of their stick, and make sure all of their passes and shots are spot on.... Hope they can get over it. Can you imagine having both Trieas and Trouba being able to bomb the puck on net??? It's bad enough for the opposition to KNOW Trouba is going to get a long shot, and be able to do nothing.
