James Harden being traded to the Brooklyn Nets last January was supposed to set up several years of dominance with three big stars in the lead. Instead, the triumvirate might crumble before it ever really got off the ground.
According to Jake Fischer at Bleacher Report, Harden might be ready to move on from the Nets once the season is over.

Harden remains invested in competing for the title in Brooklyn this season, according to multiple sources with knowledge of the situation. But Harden has recently informed several confidants —including former teammates and coaches — of his interest in exploring other opportunities outside of Brooklyn this summer, league sources told B/R.
