Like the above post lays out, I think getting Trouba's cap hit for 2025-26 completely off the books is the biggest thing he is trying to accomplish.
I am sure he would love to upgrade on Trouba, and Lindgren. But, being able to re-sign Shesterkin, Lafreniere, and Miller are big challenges that getting Trouba off the books for next season is key.
As such, retaining on Trouba, especially 50% is not the most attractive idea to Drury, most likely.
Jokiharju for Trouba straight up, and maybe with some sweetener from the Rangers, would be the most likely path forward that Drury would want to go down.
