That deal smelled more of a let's get it done rather than "I want this and I'm willing to wait to the offseason to get it"
And yes, those deals do, but thsrs just me stating one way.
You deal Hertl and let's say 2 years from now the contracts you took on are done, you can then take on cap dumps, potentially of good, just overpaid players, then eat 50% there and get an asset for taking on said player and then dealing said player.
Maybe Hertl will just be either a very meh player and/or missing time and it will look like Grier did well before selling him off. If he is that injury prone, then LTIRetirement. Maybe that's an issue ? Sharks, to me don't seem like a team that struggles and has an internal cap, but maybe that changed for the retool/rebuild.
