Stat wise he will still be in the elite level, especially in a shortened season, hes a workhorse. His whole career he's showen that the more shots he faces, the better he performs so shipping him to toronto or florida may be an actual net gain for fantasy owners (not in wins but in saves, save %, starts). He's a starter and even if kept in Vancouver will still get more of the starts over corey.
Anyways, I wouldn't avoid him at all. He's dropped down my draft list signifigantly and like most canucks fans I'm a schneider fan now but this doesnt change his skill level and stat output for fantasy purposes.
