That's fair, though I would say that is also the Bruins way of doing center at the present time, and there is no reason they have to operate that way. Poitras is probably not going to be that type of center, lack of size, not very physical, grinding down low. The Bruins need to adapt what they do to the players they have, not constantly try to shoehorn guys, especially young players, into roles and activities they are not suited for.
But okay on Merk, he may never be an NHL regular, but I would sure love the Bruins to give him a good long look and see what he can do if used properly before moving on.
