The cost for Stone was steep for Vegas: Defenseman Erik Brannstrom, 19, who was selected 15th overall in 2017 by the Golden Knights and is considered an elite puck-moving defensive prospect. The Knights also sent forward
Oscar Lindberg and a second-round pick in 2020 that belonged to the
Dallas Stars.
Hall traded to Coyotes by Devils
Taylor Hall was traded to the Arizona Coyotes by the New Jersey Devils on Monday.
The Devils received forwards
Nicholas Merkley and
Nate Schnarr, defenseman
Kevin Bahl, a conditional first-round pick in the 2020 NHL Draft, and a conditional third-round pick in the 2021 NHL Draft for Hall and forward
Blake Speers
Its hard to judge what a collection of prospects & picks turns out to be for a few years. The return for Karlsson was also a collection of assets that were actually pretty good, yet many I suspect thought the return wasn't great at the time of the trade.
I haven't mentioned Kapanen, so not sure why you are bringing that up. I did mention that imho the Rangers (a rebuilding team) may be more interested in a futures type trade.
I do agree that GMs are getting smarter than they used to be when it comes to trades for pending free agents.
