This doesn't belong here but ROR wasn't the only player who lost the will to play and asked out under Phil Housley. Also, idk about Kane, but ROR and Lehner aren't being problem kids on their current teams, right? Maybe there were other problems?
As for giving up assets, you say we should have finished higher by not accelerating the rebuild in 2016. That is one year after the tank, and finishing 25th-ish or worse after drafting Jack Eichel would not be very pleasing, and probably unacceptable by ownership standards. The bottoming out ends at 2015, then build up.
As for Bogo cap, Bogo-Myers was close to cap neutral other than term, and we had no idea he'd break down this much. Bogo at his best would be a decent asset, but he declined terribly this year.
I do still agree we gave up an extra asset too much in each trade though - however I have my doubts that this organization would have developed any of their draft capital correctly - that includes Compher and Zads. (I'd love to have one or both on this current team) Other than those two, how much help would Armia (if developed as a scoring role, unlike his trajectory in WPG/MTL), Lemieux (no leverage), Grigs (Darcy messed up), in other words the rest of the prospects given up in the trades, be?
The 3 trades themselves in a vacuum are not the reason for the rebuild to be derailed. There were tons of other mistakes, like coaching (Bylsma, Housley), drafting (Nylander over Sergachev), failed development of depth players, improper addressing of depth issues (LHD black hole)...
