I definitely would have kept those two kids! I thought King was pretty decent and Berube was as good as Wishart.
As for Kerr, he requested a trade not too long ago, well actually Daddy did. It was probably best to dump him off while he is still worth something. He will never be anything more than a stay at home D-men with some toughness, more like a guy who was drafted in the 12th round not the 1st!
