It's simple, really.
Suzuki, Caufield, Kotkaniemi, Romanov are already roster players. We drafted a ton of prospects the last four years. It's time to turn those into actual NHL players to surround our young core and take advantage of the remaining productive years from Price, Petry, Gallagher, Toffoli, Hoffman etc.
Passivity will get us nowhere. We've tried that with our previous core when we waited for Galchenyuk, Beaulieu, Tinordi and McCarron to grow into roles we had envisioned for them. It never happened. Instead, we watched Plekanec and Markov age and deteriorate and the team went off the rails.
Now, I'm not advocating spending future assets on 30-year olds. But if next years' pick can get you a Lindholm, or a Dvorak, players just entering their prime, who will help Suzuki/Caufield for many years, then go for it. I don’t see a reason not to.
