The Kovy arbitration decision, which can be found here, mentions in a footnote the following observation regarding the Hossa, Luongo, Savard and Pronger contracts:

...while the contracts have, in fact, been registered, their structure has not escaped League notice: those SPCs are being investigated currently with at least the possibility of a subsequent withdrawal of the registration.

But don't worry people! I'm here to let you all know that everything is going to be ok. There is no way in hell the NHL is going to void Lu's contract, or any of those contracts for that matter. And the reason is simple: Marian Hossa. Why? The facts are these:

1. Hossa's contract is the MOST extreme of the four, in that its terms are most similar to the terms of Kovy's voided contract that the arbitrator listed as being evidence of effecting circumvention.

2. Hossa's contract has already been in effect for a season.

3. The Chicago Blackhawks won the Stanley Cup last season in which they had the advantage of Hossa's talents while under such contract.

Thus, in order to void Lu's contract, the league would have to also void Hossa's contract, or at least admit it should have been voided but perhaps claim that since it has already been in effect for a year, it's too late, or some bullshit like that. But however you slice it, the league would have to acknowledge that the Chicago Blackhawks won the cup by circumventing the cap. There's no chance in hell they'd want to do that.

Case closed.

It took me 15 minutes to write that. At $250 an hour, that will be $62.50 please, Zandberg.
