Miami Heat rookie swingman Tyler Herro hailed new Knicks assistant coach Kenny Payne as being key to his development at Kentucky and admitted a “motivation’’ after falling to No. 13 in the NBA draft.

Herro has been a godsend for the Heat in their unlikely run to the NBA Finals as the fifth seed — a 3-point-shooting machine who drives to the basket with abandon.

The Knicks hired Payne to their staff because of his work with prospects such as Herro and two other Finals participants, Miami big man Bam Abedayo and Lakers superstar Anthony Davis.

“It’s tremendous for [Payne] and his coaching career,’’ Herro said on Zoom on the eve of The Finals.
