Why?
Unless we find an adequate 1 C from the open market, someone needs to play that position next season because the younger guys aren't physically ready. Laine needs to work hard on faceoffs, and get more repeats as C to get the positioning right but there's no reason he couldn't fill that spot.
As we can see, there's much more options on wings than centers. As he shows he can do that job, we're not going to be in a position to use him as winger next season. Center is teams weakness and this can help in that until the youth grows
