This was something Buffalo fans identified well before the season. There are just too many defensemen on the roster and not everyone can play. It got even worse when we acquired cap dump Matt Hunwick from Pittsburgh . Before the season we had: Ristolainen, Dahlin, Bogosian, McCabe, Scandella, Nelson, Beaulieu, and Hunwick on the starting roster, with Pilut and Guhle right on the cusp of making the league. Now that Pilut has shown that he's too good to send back down to the AHL, there are 9 guys in the mix to start on any given night.
Beaulieu has been fine this year, if I were the GM of a team that needed a 5/6 LHD, I'd give up a mid-round pick for him.
