No one is advocating the Buffalo you have to suck forever model (I don't think). There is nothing wrong with hoping you add a Bedard/Vlassic (upper half of an NHL roster) pair from your prospect pool and have a young guy that struggled/or was not what we envisioned take a leap ala Kurashev. Add a good (even if just a bottom pairing) RHD, a top 6 wing, middle 6 center (someone that can take faceoffs especially PK) and the waiver wire plugs/AHL level players like Entwhistle, Johnson, Anderson, Raddysh, Zaitsev, Tinordi, Menga go away from the lineup making the team better. Certainly not playoff better, but an incremental step where kids have more to develop with in the NHL, your prospect pool gets to marinate further, you add 7 more top 100 draft picks to the prospect pool (where hopefully 1 or 2 are only a year or so out from arrival). Next Summer you take another incremental step where you replace Hall, Anthanasiou, & Donato on the roster with a combo of kids and MAYBE...just maybe, if everything went well over the next year we can start fishing at the top end of the UFA market and be attractive enough to bring in a finishing piece the prospect pool has not developed internally (along with adding another good NHL player or two from the prospect pool).
There is a sweet spot in the middle between trying to cheat/short cut a rebuild by trying to trade away futures for immediate results a year and a half into it and going the continual rebuild for a decade plus mode.
