I'd take that with a grain of salt ... a lot of these 'insider information' is recycled materials, which could even trace its source back to an internet forum like ... ours.
First of all, I think 1st + 2x2nd is a fair price for Hamonic. Hamonic is NYI's #1D, and plays easily as a 2D-3D on most teams in the league. He is 29, very much in a dman's prime. He has 3 more years at a VERY cap friendly number ($3.85M? anyways it's under $4M, way under-priced for a guy like him). For a RHD with that kind of resume, I believe a 1st + 2 x 2nd is a fair price. I think CGY paid market value.
My question is - What is NYI trying to do? First of all, why are they trading Hamonic to begin with? I still don't have the answer to that. Is it because Hamonic wants to be close to home? (2 years ago he reportedly asked for a trade to the west coast to be close to home because of family issues). And if that is the reason, why is TOR even in the mix?
Beyond Hamonic, what is NYI trying to do? Are they in the 'compete now' mode? Or semi-recalibre mode? By giving up a 1st to take Grabo's contract and protect their roster players, they seem to be in compete now mode. If that's the case, why would they accept CGY's offer of pure picks, and no roster player? I don't see a direction to the moves NYI makes.
As for Leafs' offer, I firmly believe JVR is on the table, which makes sense. NYI needs scoring help, and JVR will look very good on Tavares' wing. JVR also has 1 more cheap year left before he turns UFA, and this allows NYI the cap space to 'compete now' (if that is their direction). JVR is from NJ area, so going back to NY is kind of going home for him.
I doubt the Leafs offered JVR + 1st, because if CGY's offer is 1st + 2x2nd, then JVR 'replaces' their first, and it would be a JVR+2x2nd offer, or JVR+B player (like Leivo) + 2nd. That seems more likely to me.
In the end of ALL THESE though, I still have no idea why NYI traded Hamonic. Hamonic seems to be a player NYI can use either they are in compete now or re-stock mode. I see no reason why NYI traded him, except he still wants to go back home to the west coast, in which case the leafs have no chance to begin with.
