Larsson/Hall- like for like. 24 year old top line wing with 4 years of team control for 23 yearold 2/3D with 5 years of team control.
Jones/ Johansen- like for like . 21 year old top 4 D with top pair potential in last elc year for 23 year old emerging 1C in second non elc year
Hamonic- 27 year old top 4 D seasons from UFA for package of lesser futures.
Of your three examples two are non-applicable based on contract status/ asset type, and one was contrary to your point. Still waiting for three examples (I'd be impressed by one really) of a player like Tanev (27 yearold 2-3 , in his 3rd season before UFA) returning 1 big young piece. That's all I'm really saying, that a 1st+Kapanen+ Carrick is a reasonable offer, and that the "that's not even close" and "1 big young piece" are not realistic
The difference between Larsson and Tanev isn't that huge. Tanev isn't that old, he still has many years of play left. But I thought I'd look around for trades on non-expiring contracts and honestly (i didn't go back that far) but I didn't find much. But a couple of blasts to the past, things I found interesting - not necessarily examples that can be related to Tanev:
o 2012/2013: Bouwmeester for Cundari, Berra, Cond 1st, Cond 4th.
o 2012/2011: Burns + 2nd for Setoguchi, Coyle and a 1st (28th)
o 2011/2012: Turris for Rundblad + 2nd
0 2011/2012: Zidlicky for Foster, Palmiere, Veilleux, 2nd and Cond 3rd.
Any trade involving Tanev is going to be difficult, because it's going to be mostly unprecedented. A trade will most likely be very close to the Hamilton and Hamonic deals. Something like a 1st and a 2nd.
I'm happy with a 1st and a 2nd coming back, but the 1st has to be at a suitable spot. Anywhere around the 20 mark is good, but too far back would be bad asset management. But since you can never guarantee the spot and since Tanev will most likely make you a better team, I'd ask for some assurance.
Kapanen isn't a need and not a very attractive piece to a D and C lacking prospect pool. I just wouldn't target him.
