I guess the likely thing is that LA has tried, and he hasn't shown any interest in coming back any time soon. If he's coming over in two years, I guess they'll likely have lost the rights to him, so no reason for LA to deny other teams the chance to talk with him.
What do you mean by fell?
Depending on when the Kings lose his rights, he could still be a trade target. If he wants to wait until his contract is over, he could come over at 25. If they have his rights until he is 26 or 27 that would give them some time to negotiate. Obviously, the value wouldn't be high on an asset with that intention. But, he could be another bullet in the chamber. Some of the guys the Leafs don't intend to sign could be swapped for his rights.
I'm assuming he meant fell due to the fear that he'd never stay in North America. Pretty common with Russian prospects. From what I remember Tarasenko was seen as being worthy of a top ten pick but due to his passport, fell in the draft. Again, pretty common with Russian prospects. Saw the same with Kuznetsov. These guys were both great prospects but nobody would gamble a top pick on them. Gotta wonder what happens when the next great Russian prospects comes along. Will anybody be willing to use a top 5 pick on one? It's hard to see
