Quoting: phillyjabroni
December 29th, 2016 : Artemi Panarin signs a 2 year 12 million extension with the Chicago Blackhawks.
June 23rd, 2017 : Artemi Panarin is traded to the Columbus Blue Jackets.
Had Panarin not signed the extension, he would have hit the RFA Market.
This is an example of what it would mean to have a sign and trade. You theoretically signed the player during the regular season, and then traded them in the offseason.
Player was already their property though. (RFA) (Late edit: pending UFA's are presumed to be no longer that teams property, at least for this game's purposes only) That's the difference. What sign and trade is being interpreted here is for UFA's only:
GM: Hi Oshie! We really want you here in Montreal and think you'd be a solid addition to our team who hope to go for the cup.
Oshie: Ok that sounds good I like where MTL is headed and want to be part of the team! Sign me up.
GM: Ok just sign here aaaaaaaaaaaaaaand by the way I just traded you to Colorado for a 1st rounder.....enjoy the skiing in fun town!!
Let me preface this by saying I think under the structure of our game and what the essence is, sign and trades
should be allowed. Like I mentioned, Brian Dumoulin was traded 17 times this month but no one bats an eye. A GM wants to sign Oshie just to trade him for picks afterwards, No that's not allowed.........
That's the thing, we are picking and choosing our rules as we go so we have to take liberties with some circumstances. If Vegas wants to spend all there available cap on free agents just for the purposes of trading them afterwards, that should be there prerogative. It's technically legal in every way. What is the counter to that from the rest of the GM's? No one trades for those free agents and Vegas is now stuck paying Oshie, Shattenkrik and Hanzal 20M of his cap because no one wants to bite on his trade demands and even if they do, he might have to retain salary for it to work.
