I think EK was saying it'd be weird with 3 days left to go before the trade deadline to ask him to waive. It probably wouldnt be enough time for EK to do his due diligence before accepting a trade. I get the sense there's not a lot of communication that is happening between the GM and his players.
Why would you bother having that difficult conversation with your star player if you aren't going to trade him.
Sure something last minute could spring up but sounds like Edmonton has decided against it this year so don't think there is a market. (maybe the offseason though)
