Glass might have it in him, he's really been turning it up with Duchene, but he's not a guarantee type guy though.
Parssinen is so young it's hard to tell, I'd put him around the same probability as Glass with a different skill set.
Novak, probably not. Decent 2C or really good scoring line 3C.
It's a really good set of young centers that I'm thrilled to be watching. I can still see Trotz using all this draft capital and prospect depth to pluck a sure fire 1C from someone, or attempting to anyway. Maybe it's a team that already has good top 1 and 2 centers and doesn't want to pony up for a sure fire RFA and he packages Novak and other stuff. That give the other team a solid 3C and some draft capital.
Edit to add: We Preds fans are so used to not having decent centers, a wealth of draft capital, and quality prospects in Milwaukee that we don't think about going out and buying a huge name guy. It's always, "we'll have to mortgage the future for one guy that won't put us over top". We'll, that's not the case right now, Poile has this team in maybe the best position it's even been in to BUILD a team.
