It goes both ways - Nino queered his value while Vanek failed primarily in hindsight. I wouldn't have traded the picks, but I understand the risk.
I will say this much, though - even if Buffalo is working under the premise of moving everything they just acquired for Miller and Ott, that GM grinds out a trade. Miller was worth 2 of those pieces in my opinion, but Ott wasn't work the other two, though I could be underestimating his value.
It would be nice to see Snow win an actually trade, because even as a "different" brand of realist seeing where the financial lethargy of the franchise leaks into every aspect of the overall picture, that absolutely needs to be improved.
The Islanders may not be quite as bad off if Snow were better at trading, but given the justification behind the opinions of those of us who see the failure at 75%/25% on Garth's worst day, I think the difference is about as far off in negligence as blaming the tires on a car with a fried computer. Lowers the value, leaves more to fix, but you still need a new card all the same.
Regardless, he could stand to flat out "win" a trade. Nino for Clutter doesn't singe me, Zhitnik for Meyer when Zhitnik could have had Brayden Coburn does.
