I've always felt that he was one of those guys who is far more valuable to a specific franchise than to any other, kinda like how Jovo, Ohlund, Linden, Salo, and so many others went off a cliff when they left Vancouver.
At the time he left, I personally took 40-point defensemen for granted, because it seemed like the Canucks always had one or 2 crack 40 points every year. Since we lost the Hoff, Edler's had the only 40+ point season from a Canucks dman.
He undoubtedly left us in his prime, and immediately ran into injury issues and a god-awful fantasy league-contructed franchise in Buffalo.
A big part of me wishes they'd given him his $5 mil/year and skipped the Garrison experiment.
