Bellows is another sniper who needs a playmaker to get him the puck, as Bondra said, he doesn't make his linemakes better but he can close like Hoffman. Brown on the other hand is an excellent playmaker like Spezza who can make his linemates better with a perfect pass for an easy goal. And just like Spezza the way he plays will piss people off but like Spezza, Brown will have to keep producing pts consistently to keep people off his back since he will never look like he is trying hard enough for some people, me included.
IMO Brown's size, reach & weight will be difficult for a lot of centres & defencemen to handle in the offensive zone & around the net. Mathews is not going to be able to push his way to the net against Brown as easily as he could against Turris, as an example. Of course, they will need to convince Brown to play at both ends & if he can do that I expect he could be a significant player for this team's future.
