They don't need to burn everything down, the Rangers didn't. They moved out a bunch of guys, then moved in a bunch of younger guys:
Gorton actually presided over the rebuild:
6/23/17 Stepan and Raanta for DeAngelo and Zona's 1st (unprotected), became Andersson
2/25/18 Nash for Spooner, Lindgren, 2018 1st
2/26/18 McDonagh & Miller for Namestnikov (traded for Ebert & 4th), Howden, Hajek, 2018 1st, 2019 2nd
11/16/18 Spooner for Strome
2/23/19 Zuccarello for 2019 2nd, 2020 3rd
2/25/19 Hayes for 2019 1st
4/3019 2019 2nd, 2020 3rd for Fox [that wasn't brilliance, that was Fox forcing his way to NYC]
6/17/19 2019 1st, Pionk for Trouba (then gave him 8x8)
2/24/20 Skjei for 2020 1st
9/26/20 Staal & 2nd for cap relief
10/7/20 Andersson for 2020 2nd
Drury
7/17/21 7th rd for Goodrow (took his salary off TB's hands)
7/23/21 Buchnevich for 2022 2nd
3/16/22 2022 4th for Vatrano - best TDL move
3/21/22 2023 4th for Motte
3/21/22 2022 1st for Copp
3/21/22 2023 3rd for Braun
Key was drafting Shesterkin in 2014,
As far as all those draft picks they traded for?
2017: Andersson #7, Chytil #21
2018: Kravtsov #9, Miller #22, Lundqvist #28
2019: Kakko #2
2020: Lafreniere #1, Schneider #19
No one after the 1st rd has emerged so far.
Notice they didn't trade that well, the TB trade was highway robbery, Trouba was basically obtained for Pionk and Skjei. They gave away Buchnevich to St Louis.
The key deal was getting Lindgren and Spooner for Nash, then flipping Spooner for Strome.
Point is you don't have to conduct a rebuild with total brilliance, just commitment. And a hot young goalie.
