Rich Peverley, 6'0" 200, right handed shot, listed as a center, though i'm guessing he'll wing it up with the B's.
Seems like a good character guy and hard worker, but I can't find a full profile on him.
Boris Valabik is a 6'7" Defender who can't seem to stick in the NHL since being drafted in the 1st round of '04. Perhaps learning and playing with Chara, who is a fellow countryman and sizable defenseman.
I was hopefully Wheels and stewie could both continue to grow with the B's but getting Kaberle and Kelly really can help this playoff run - and at least there is some potential in these two guys also.
