Possibly? It may just be me, but I want dynamic players on my first line and Fraser doesn't strike me as that kind of player. He has a great shot, is an average skater at best, is big (but not nearly as physical as Iginla), and goes to the net. It seems to me that he is a "nice" player, and reminds me of a guy like Ryder, who I also would not want on the first line.
I was OK with dealing Boychuk, but I was really hoping that the B's could bring back a player better than Fraser (or the other options like Gagne) as part of the JB deal or in a separate one (which still could be coming). I really like the 2nd and 3rd line combos and hate to break them up, but at this point, I think that Smith's skillset is a better "fit" for 17 and 46 then any other candidate. We could also still see Loui in that role (once both 17 and 46 are 100%). If that happened, I would out Spooner on Carl's left and Kelly on his right. The easiest solution would be if one of the internal candidates like Pastrnak stepped up and filled the spot, but I'm not sure he's physically ready for that role?
