The Phoenix Suns and New York Knicks have discussed a Kristaps Porzingis trade, but talks haven't gained traction due to Ryan McDonough's refusal to part with Devin Booker.

Booker averaged 22.1 points per game in his second season though his True Shooting Percentage dropped to .531. Booker scored 70 points in a loss to the Boston Celtics in March, which further cemented his standing within the Suns' organization.

Booker won't turn 21 until the end of October as he was one of the youngest players of the 2015 draft class.

The Knicks continue to consider trading away Porzingis, focusing on teams at the top of Thursday's draft.
