I'd cut him loose. CBJ looks awful so far (again, even with their high priced additions). Even when the Wiz is back frm his suspension, he's not really noted as a defensive spe******t.
I like Varlamov the best out of the guys you mentioned, though...injuries are a concern. I think the Avs are better than many suspect and as long as he's healthy, he's the clear #1.
Good luck!
