Devils reject easily. Vatanen is playing some of the best hockey in his career and is on pace for more than 50 points. Plus he wants to re-sign.

Yeah, I'm a Leafs fan, and want Vatanen, but this trade is some kind of crazy!

I was thinking Vatanen for Ceci also, but with Timashov, Bracco and a 2nd to make it worthwhile. Both veterans have expiring deals. What would NJ say to that rental? They don't stand to benefit from winning this year, and flip Ceci as a rental to a team with a bit of deadline cap space...

Shero declines.. Add a prospect to the 2nd and take out that 4th.

Doesn’t Ceci suck? And I don’t think unless NJ gets a lucerative offer they are trading Vatanen

Yes, Ceci isn't great. That's why a couple of real prospects and a 2nd are included in the rental. Certainly shipping Ceci out at the deadline would add something else to the haul for Vatanen rental.
Interestingly, after I wrote that, Richu2 was looking for almost the same trade, but a little less even!
