his own fault
"Why didn’t we ever feel sorry for Carmelo? It’s simple — he placed himself in this situation. He could have waited until the summer of 2011, opted out of his first Nuggets extension and signed with New York as a free agent. Instead, his agents forced a midseason trade that kept his previous contract in place (more money, more leverage). Here’s what that extra money effectively cost them (and Carmelo): Danilo Gallinari, Wilson Chandler, their 2014 first-round pick (turned out to be 11th overall), and a first-round pick swap in 2016. Four super-tradable assets … out the window.
A few other players were involved, including Felton and Timofey Mozgov (sent to Denver) and Billups (sent to New York). And that’s where this deal gets darker. After the 2011 lockout ended, the Knicks used their amnesty on Billups solely to create cap room to sign Tyson Chandler. When Amar’e degenerated into The Artist Formerly Known As Amar’e two seasons ago, they didn’t have an amnesty left to snuff out his remaining $40 million. Whoops. Unable to improve their roster last summer, they stumbled into the comically bad Bargnani trade. This summer, they couldn’t sign any impact players.
All in all, that was a catastrophic trade considering Denver didn’t have any leverage whatsoever. And it happened because Carmelo wanted more money"
