I think Melo is the cause of all his issues. He should have not helped his team get to the playoffs for 2 straight years so Denver could collect high lottery picks to add to the core. Instead, Denver was stuck with low first rounders to build around.

Durant did it smart. He didn't get his team to the playoffs his first 2 years in the NBA allowing OKC to draft Russell Westbrook and James Harden.
If he had just simply not been good enough to get his team anywhere those 2 years he might have gotten to play with Dwight Howard and Chris Paul/Deron Williams.
He comes here and leads this team to the 2nd seed in the East when really we needed a high lottery pick.
Melo was/is too proficient for his own good.
