The New York Knicks hired Brian Keefe on Tuesday as an assistant coach.

A source says Keefe is very close with Kevin Durant, who will become a free agent in 2016.

Keefe spent seven seasons with the Oklahoma City Thunder, the first two as a developmental coach before being promoted to assistant coach.

“He’s Durant’s guy,’’ the league source said. 

During last season, Durant noted Keefe had put him in his place regarding body language and attitude.
