This is true, but also I wouldn't be surprised if the Sharks created a roster spot with the intention of all but giving it to him. I mean, they essentially didn't pursue a defenseman at the beginning of last season because they wanted Mueller to step in. They also basically counted on Hertl to step in two years ago (although this was warranted; I watched a lot of Hertl during the lockout when he was playing in the Czech league and it was clear to me that his floor was 2nd liner and that he was NHL-ready).
I really really hope Meier pans out. I really do. While the Hertl-Thornton-Pavelski line is nearly unstoppable, I've always wanted Hertl to develop as a center and I think Meier will be capable of doing a lot of the things on that line that Hertl does right now. Meier is a big body, good hands, really strong, good shot. If he can adapt to protecting the puck against NHL defensemen quickly, I think he would be a great fit there as soon as next season. If not, he could slot on Couture and Donskoi's line, they'd be a great for for him too. Or he could play with Tierney on the third line, that would be a great fit too... Meier seems to be a well-rounded player whose skillset complements many current Sharks.
Adding Meier and Goldobin to a forward corps that already has Thornton, Pavelski, Marleau, Couture, Hertl, Donskoi, Tierney, and Ward... Man that's a ton of skill. I don't want to rush either if those guys, obviously, but as a hockey fan it's hard not to get giddy thinking about that.
The more I hear about Meier, the more he does seem to have the potential to be a true Marleau replacement, even if he's not a true peak-Marleau (2009-2011) replacement, right down to the streaky even strength scoring and occasional floating.
