The price may be going down as team's solidify their rosters and some teams try to become cap compliant.Chychrun is the best option. I bet the price has gone up quite a bit with less and less RD available.
Maybe something like:
Formenton
Thomson/JBD
Wash 2nd 2024 (Acquired Connor trade)
Ottawa 2nd (2025)
For
Chychrun
Zaitsev (1 mill retained/year)
At this point team rosters are kind of set, Kadri and Klingberg are still out there so there is the potential that a roster or two gets shaken up a bit, but I think most GMs are in "let's see what happens" mode.
I wouldn't be surprised if we start the season with our roster as-is and the hope is something happens somewhere (injury, a team underperforming) and we can find a way to pry a RD out of it.
Some GMs might be waiting for the non cap compliant teams to get desperate and make a trade to get under the cap. There is no rush to get it done; however, the number of teams with cap space will slowly decrease.
