I think its his processing speed of the game. The OHL he's the man there is more time and space and he does a lot off the rush on his own. Here you need to read and react and move the puck to the open man at the right time and move to support the play. IMHO he does not process the game .. In the Russia game I think it was Newhook that passed it to him on an entry and then broke for a give and go and Byfield didn't get it , didn't see it. Last night vs Germany he got the puck in the corner and was trying to stick handle by players while standing close to still rather than making a short pass to the open man.. His utilization of his team mates and how to play off his team mates is lacking. Now again .. its a small sample.. there is an adjustment to make . I hope he can make it but its a short tournament. I think the 4th line energy role he had with Zary and Mercer vs a good team, the Russians, is where he needs to be at this poiint.. Keep it simple get it low, work, forecheck hit, support in battles. I also don't think Quinn has made the adjustments .. he can score we know that.. but this team is about pressure, winning battles and moving the puck quickly .. he is struggling with that as well.
