Okay so now I can answer some of these questions...sorry about the delay. I'll be honest in that I haven't seen enough of Lavoie's game to be able to rank him yet. Our organization is very high on him, and has him at #10 in our recent rankings. However, at this point I'm not able to make an informed decision on his game.
Broberg on the other hand...I've been watching him since the Hlinka Tournament. There's a lot to like about Broberg's game. He has some great size and skating speed, but his decision-making and overall "hockey IQ" are suspect in my opinion. He has a very strong shot from the blue-line and is relatively safe, defensively. Teams will fall in love with his size and skating speed, especially since there aren't too many defensemen near the top of the draft class, but the lynchpin to his development is the IQ since he has all of the other tools. There is potential there, but is it worth the risk? Especially the risk of a top-10 pick? I don't think so at this point. He'll likely be off the board by the 15th pick though. We'll see how the season progresses.
