Get your tin hats out, conspiracy theory coming in:
I still can't imagine why Lou would sign the papers and leave Kovy scott free to sign anywhere he pleases outside the NHL. It just makes no sense; Lou's being majorly taken advantage of if he just decided to do it to be a "good guy". Hockey is a business, and that's not how business works.
Here's the conspiracy: someone from the KHL essentially bought Vanerbeek out. It's no secret he's not exactly wealthy anymore, and it's no secret there's a stupidly large amount of money in the KHL between a few owners. it could easily be quietly done, and Lou would have no say in the matter if JVB gave the orders.
I know it's absolute nonsense, but hey, why not share it? It sounds just as absurd to me as the theory that Lou didn't want to sign Kovy in the first place.
Equally likely conspiracy theory is the Devils think Kovy's back is shot and are secretly relieved to get out of his contract.
