Not really if they had no intention of using him and have no people coming in
To change up the roster though? Weird logic to use when firing someone, unless Sandow wasn't contributing anything at all since his hiring, and I'm pretty sure given the majority of IWC's salivating over him, he did contribute something.
Could have easily changed his character or something, as they miserably tried to do
Could have been the mouthpiece for the Vaudevillains turn him heel and refer to him as MANdow, start up a Gentlemen's Fisticuff faction with them and Cesaro.
