(maybe a 4th too, depends on clitsome value)
Prospal.. well easy one. Boston gets upgrade on 3rd and fillin top 6 for depth (if needed) plus a vetern presence.
As for Clitsome. I think he's an upgrade to Kampfer, but basically because of experiance. Plus I like'm reminds me of a younger version of Sids and I think he'll do very well under Julians system in boston. Plus he's been a healthy scratch in CBJ so shouldnt be expensive to move at all.
in return columbus gets two NHL ready rookies. Caron is a gritty player that will do into the corners and dig the puck out and kampfer with some icetime will eventually develop into a better player PMD then Clitsome, IMO.
I know its not ideal, but it fills bostons wholes I think making them possibly better next year as well without giving up huge assets and in turn makes Columbus younger and a little more gritty with some future talent in the back end with some ice time.
Not a bad trade for either team in my opinion although Clitsome wouldn't be my first choice as the 7th dman but Prospal would be a nice addition for sure.
I know clitsome is a more realistic low end approach to bostons back end 7th but I think he could be a diamond in the rough for boston. He plays and reminds me of a slightly more offensive minded Seidenberg. The guy hits, blocks shots and has the defensive willingness to him which i believe makes him a good fit in bostons defensive system. A more defensive minded PMD. cheap cap hit. Plus with the loss in favor in the CBJ camp should come pretty cheap, that and cbj doesnt seem to be hurting in the D, department either.
