And no sooner did I post about Greig, that someone sent me a PM about him. They're cool with me posting this here:
Q. So why don't you think Greig sticks at center? Where are your concerns?
A. The short answer is that I am unsure if he sticks at center. I think he's creative enough to play there, I think his overall instincts are really good. But there are three areas that concern me with Greig as a center and not a wing.
The first is faceoff ability. Like Bourque, and what seems like a long list of forwards in this draft, Greig has struggled in that department. Sticking at center can be hard enough for guys who have a knack for those types of details. It's even harder when they're not mastering the art against teenagers.
The second is some of his decisions at center. There are times Greig borders on forcing a play or doesn't always make the best choices at center. Some of that could be experience, but I found it to be less frequent when he played on the wing. I don't totally know if Greig is the guy I want setting up the play on a primary offensive, so much as the guy who gets himself into position while playing with someone who is a little more consistent in the regard.
The third concern is whether his size/strength, even with maturity will work as a center in the NHL. That's potentially less of a concern if you view him as a second line center, but it might be a little more of an issue if you're eyeing him for a third line role. It also depends on how you project his physical growth. It's not impossible for him to reach 6'0, 190-200 pounds at the NHL level, but that's going to take some time and patience.
None of these are reasons not to draft Greig, who is a very good prospect. I just think you have to account for these elements when determining value, draft position, and projections. To the latter point, I'm not sure Greig has quite as clear of a trajectory as some of the other options. However, he definitely has value and legit NHL potential.
