If I may wade into the fray here.... I'll admit up front this is about 95% speculation on my part
Not saying I agree with it, but if there's a d-man on Vancouver who is available, it's Hutton. I don't think Green really likes or trusts him, he's been a frequent healthy scratch, and his name has been in rumors before. Now, we can debate his value and upside till we're blue in the face, and I don't see him as a guy Tampa would want, but if there's a guy I can see Benning moving out, it's Ben...
But to play along, if Edler were to waive, I'd probably agree that he'd want to go somewhere where there's a good chance he could re-upp when his contract expires. I don't think Tampa is a fit, as they probably want to keep financial flexibility for when guys like Kucherov/Point/Vasilevsky need new contracts
That said, Edler is a de facto top pairing guy on a weak defense, quietly having a solid season and he elevates the play of whatever marginal player he's paired with (Gudbranson, Pouliot and to a lesser extent Stetcher) ~ I'd absolutely want a half decent asset or two in return, given our defense is probably the worst in the league without him
One last point.... A lot of the speculation around Tampa has them getting a guy like Green or McDonagh, but I think the darkhorse trade target (the guy I'd be going after if I were Stevie Y) is Hjalmarsson... Underrated player imo, I know he doesn't bring a ton of offense but I've read a few times on here how the Hawks miss his stretch pass ability (amongst other things)... Seems like he'd be a natural fit in Tampa... Isn't a pure rental like Green, can play either side, very reasonable contract that expires at just the right time, would probably (hopefully?) waive to go to another top team and get another crack at ol Stanley and wouldn't cost as much as a guy like McDonagh... But that's just my $.02, and if 'Zona was smart, they'd probably keep him
