While the Knicks could offer the Suns a center like Mitchell Robinson or Karl-Anthony Towns, Phoenix likely wants draft capital in a return for Durant. New York is a little strapped for draft picks after acquiring forward Mikal Bridges last offseason.

Brian Windhorst discusses additional teams, beyond Durant's top picks of the Rockets, Spurs and Heat, that are showing interest in him.

San Antonio has made it abundantly clear that they are unwilling to part ways with Castle or Sochan, both of whom have become integral players in the Spurs' plans.
