Yeah, it probably sucks to some extent that he's moved away from Florida. But he's also had massive struggles with OCD that have actually required help from the Players Assistance program. You know what sucks for a goaltender who has OCD? Being in your first full season in the NHL, playing for a contender, and knowing that a single bad goal or game can effect your standings and chances at winning another cup, let alone potentially playing in a big playoff game if something happens to Bob. Hell, it's stressful for any goalie to be in that position.
Here, though, he can grow his game without worrying about getting blamed for a bad performance. Without being a whipping boy for the fanbase. He can play with guys closer to his age. And he can potentially be a starter in this league next year here, something that might not have been possible with Bob in his way on the Panthers.
Not to mention a lot can happen in a few years in this league. Florida won't stop being a playoff team anytime soon, but by the time he'd be taking over that starter role down there, who is to say they'd be perennial contenders? Ekblad has gotten worse each season and is likely not getting re-signed. Forsling has been awesome for them, but how long is his prime? If Jones is the 2nd best defenseman there, or worse for them their best, how much of the version of Jones that we all know and hate will be present? How much do consecutive, long playoff runs effect the bodies of guys like Barkov and Tkachuk.
This trade might end up putting Spencer in a better position to be an NHL starter for a perennial cup contender than if he stayed down there. Some things have to go right for us and wrong for them, but it's not out of the realm of possibility that, years down the line, people talk about how great this move was for his career.
And if not, he's still getting paid like a starter and playing in the best league in the world. A lot to be happy about IMO.
