I also heard that (real quote) but I don't really believe in that scenario tbh.
Below us are:
ARI - Will they really pay us something worthwhile if they know we want a fwd and they want a LD, and they are the very next pick?
OTT - We won't want to be dunked on by OTT for a decade, for giving a better pick to a direct competitor.
SEA - They're lean on other interesting picks to move up. They do have a few recent prospects picked 30-45 that are turning heads but if you want to flip em to a team in the 15-20 range you need to know their preference and it gets complex.
CGY - If they move up it's likely to snag Iginla, and that doesn't help your case. I don't think they need to move up to grab Yakemchuk if we're assuming they love their local talent.
NJD - We're already at 10 and I think that's too big of a drop for MTL to consider at this point. But for the sake of it, they're also lean on picks and I'm not a fan of Holtz or the rest of their prospect pool.
BUF - Again, pretty big drop, and they don't need an LD. Gotta wonder if they'd put a Kulich on the table tho.
Add to that, that you basically have to make both trades concurrently (trade down to get asset, 27OA + said asset for 15-20OA) while the team is on the clock (because you only consider a trade down if your forward targets are officially gone)... unlikely.
