Asset management is about getting the best value out of all of your assets in aggregate, not just completely ignoring risks and opportunity cost to obsess over squeezing every penny out of every single asset.
If this trade is selling low on Edmundson after he's had consecutive major back injuries, what would selling Harris after 75 games or trying to move Savard with 2 years left under a flat cap be? How is that not even worse if our goal is supposed to be not selling low? Am I really supposed to believe that the balance of probabilities suggest that 30 year old Edmundson who has had major back injuries in consecutive years is more likely appreciate in value over the next 8 months and beyond than Harris? Not entertaining the Savard thing, it's a flat cap environment and a serviceable 2nd line C in Kevin Hayes retained to just 3x3.4 wasn't even worth a 5th.
To borrow a phrase, maybe I never f***ed the prom queen, but I don't think I would have got much action in high school if my strategy was to dump my girlfriend and sit there with my dick in my hand hoping that the prom queen who flaked out on me two years in a row will be my date in 8 month's time.
