There's a fair bit wrong here....
First of all, the idea of a top 6 LW being the Ducks weakness is outdated. We're perfectly fine with Rakell, Cogliano and Ritchie manning the left side in our top 9. Rakell can also shift to RW if needed, meaning the Ducks can simply target the best fit available.
"Jones is there because you are trading from a position of strength, for a weakness..."- this part makes no sense at all. Obviously the point of any trade is to improve and balance one's team, that doesn't mean the Ducks need to kick in extra value.
So putting that nonsense aside, the Ducks are moving Jones in order to upgrade rental goalies. That part doesn't work whatsoever. We can't afford to keep Bishop (contract or expansion), and our GM doesn't move his top young pieces for short term gain. Anaheim is one of the last teams in which you should be considering when trying to figure out where Bishop is going, it's not any sort of fit whatsoever.
