Garrioch has the same successful prediction rate as psychic nikke, miss cleo, redbull and a few other posters on HF. This is mindless speculation at best.
I'm not sure Yandle is something the Islanders need. They have more than enough small, offiense first puck-movers and Yandle's not better than any of them without the puck....It's a "side-grade" for the Isles.
So if the deal is, say, Bailey-Donovan-PLUS for Yandle - then I'm not sure it helps the Isles that much.
I think another team, with a more pressing need for a puck moving dman, would make more sense.
I'd rather deal, say, Strome & Donovan for OE Larsson! ooohhhhhh!
