What will Hertl's next contract look like? He is 28 years old. 7 years? Probably. I get the sense that both he and Strome are looking at 6-7 year deals somewhere to keep the cap hit down. That and teams are going to rely on the fact that once the players pay escrow back, the cap will jump pretty quickly.
I struggle with the idea that any trade for a rental, such as Hertl or Miller even, is worth the cost to acquire them AND lose Strome for nothing. They aren't clear upgrades. If the plan was to add a forward like one of them and re-sign both Hertl/Miller and Strome while moving someone else, I could get behind that. The concern becomes which of Kreider or Trouba are you moving and where, along with what are you getting.
