This is a long Schedule and I fully expect him to play center for at least 15 games because I also expect a crap tone of injuries.
That being said, it's obvious that right now MT shouldn't even touch the EGG line because of their hot streak/chemistery. But, I will admit that Galchenyuk isn't playing that good on that line. In fact, he never touches the puck and it drives me crazy. But when he has the puck though, 9 out of 10 times it's an amazing play. Unfortunatly, Eller is always controling it and Chucky can't do anything about it.
The game at Québec vs Carolina showed me a lot of things about him. He was centering his line and he was so vocal, always had the puck before passing it to his teammates, making great defensive plays, he was the general of that line and he looked ready. But he was playing with Prust-Thomas so... That's why I think the EGG line won't last long. As soon as either Eller-Pleck-DD gets injured, I'm pretty sure Chucky will replace them BEFORE Briere and when the injured player will come back, it will be hard to move Galchenyuk on the wing, because MT will know he won't have the same impact, he won't make his teammates as much better, he will be more quiet, etc. Maybe THAT will be the right time to trade a centerman.
Galchenyuk needs to control the puck, he said it and he improved his body strenght. But, it seems he can't do that on the EGG line, even if he still finds way to get pts.
