Also I just noticed that Arizona's bid for Filppula was retroactively disallowed due to roster space issues. If that makes my buyout discount invalid then I think this trade should stand and Rudophs Balcers should be released as an invalid bid because these two moves occurred first and should be processed first.
Technically, with my extension of Carpenter and buyout of Filppula, I had valid cap space when I made the trade and it was approved.
