im having troubles seeing why Vancouver would want Hodgson back? He had a down year and left on a sour note and from what I understood, that was the reason for the swap with Kassian.
The sour note was after the trade, and on the part of the then (since fired) GM.
Going far back (pun intended), Hodgson had a back injury pre rookie year which the then coach (AV, now with Rangers) suggested via the media wasn't legit. Second eval by doctors discovered legit injury and took Hodgson what, a year? to fix, rehab and return (fyi: suggested reason for change in play from his scouting as a top tier two-way centerman). So yeah, coach was shown up to have put foot-in-mouth, but Hodgson never made a deal of it.
Going forward, kid was doing well, getting broken into the league properly in a sheltered 3C role but still putting up poitns, rookie of the month, etc. so the typical Vancouver media started nattering to question why he wasn't getting more ice time (incidentally - media just played the same crap with another Vancouver rookie this season; manufacturing drama).
Then, long after the Kassian/Hodgson deal (when the Canucks were booted from the 1st round of the playoffs arguably due a lack of offense) the media resumed its negative attention on the GM's decision to trade the offensively talented Hodgson for a non-NHL ready Kassian. Eventually the GM deflected that negative attention onto the player (Hodgson) with two sentences that inferred the kid was a character issue for some unspecified reason.
For his part, Hodgson was notably shocked at the time of the trade and afterward never spoke a bad word of anyone. Meanwhile some media played it up for drama effect and formerly big Hodgson fans became disgruntled (omg, how dare a kid not want to play for God's Gift The Canucks?!!!), starting the whole "Hodgson's daddy demanded ice time" crap.
Anyway, *if* there was ever a problem, it left with the former GM and coach. Only ones who might have a problem would be Hodgson whose rep was trashed (but who wouldn't have a say in a trade anyway), and some average joe fans who loved him then loved to hate him and would learn to rationalize loving him again. After all, God's gift to hockey is all things related to the Canucks, don't ya know?
