In that link Friedman says flat out that the Isles asked for Trouba and the Jets said "no", for what it's worth.
Hamonic made his trade request in the preseason and was shopped around the league.
In Nov. Friedman broke the story, including the news Snow asked for Trouba.
If was only AFTER the Canadian press later reported Trouba had high contract demands and an agent with a rep for messy contract disputes.that Staple and Friedman would report the isles changed their minds, no longer wanted to trade for Trouba.
In the last link I provided. Staple discusses Snow"s hardline approach to rfa contracts.
