There used to be a negotiation window but that was recently removed.
You can argue that teams violate this. I doubt that they would be this brazen.
This more sounds like the work of an agent trying to put pressure on the Avs.
I guess an alternative would be some Rags, say PR person, slips info to the media at the behest of management. Technically that would violate tampering rules but would be nearly impossible to prove. In that case the goal would be to signal the Rags’ interest to Kadri’s agent. Still a far cry from a done deal.
As I said, it might still happen. Just don’t see things as being as far along as being claimed.
By the way, if Seravalli is so confident, I don’t see him writing this down anywhere. I assume he stated this on some tv or radio show. I don’t even see a tweet to this effect.
