I agree about letting too many assets lose too much value/walk for nothing. But that is often a part of a (wannabe) contender teams/win-now approach. You have no/very little room to give them NHL time to develop their skills and showcase them, so...the only real alternative is trading them while they're still relatively fresh out of the draft. But how many of us would want that? We hated DL for doing just that in his later years - mortgaging the future for failed win-now attempts, despite the fact that he actually proved he CAN build a (multiple) Cup winner.
Besides, how many teams have proven this ruthless, loyalty-free, dumpster diving wheelin'-dealin' works as a way to get to the Cup? Vegas and Florida, really. That means there's 97% NHL GMs out there who don't know how to do that. And Vegas couldn't do it without LTIR cap circumvention either that will soon be (hopefully) impossible to pull off anymore.
And I've been saying Ken doesn't know how to do this wheelin' and dealin' any more than Rob does and it looks like he won't attract many more good UFAs either, so...yeah. Replacing Rob with Ken will most likely be pretty much a wash performance-wise (unless QB, Clarke take very big steps forward and Greentree slots right in as a 2nd line threat) and we can only hope he won't sacrifice MORE future than Rob did in the process of failing to build a winner in the short-term.
