100% agreed. In 2-3 years when Willander and D Petey might be core pieces, 2/3rd of our top line will likely be exiting their prime (Miller and Boeser), with no real replacement for Miller's contributions in sight.
People treat this team like the typical young team who's contention window just opened, but they're forgetting the core's age. Realistically, we should've been making the playoffs from 2019-2020 onwards given the core pieces we had in place & where they were in their development, but management was absolutely dogwater at identifying complementary pieces on the bluelines, in the bottom 6, or a good coaching staff.
Unless you're of the belief that this core just isn't good enough, or that you'd rather just make the playoffs every year instead of contend, this is the time to go for it.
