Mike Woodson and J.R. Smith exchanged heated words after the New York Knicks' win over the Chicago Bulls on Wednesday and the head coach chided the guard's shot selection, according to a source.

Woodson also became upset about something Smith said on the bench Wednesday. Smith made a lewd comment, according to the source. Woodson waited until afterward to express his disappointment with Smith’s attitude and reminded him that he’s been his strongest advocate for the past two seasons.

“Mike said that after all I’ve done for you I can’t have you talking back to me like that,” the source said.

During Thursday’s practice, Woodson used the game film from the win over the Bulls to demonstrate moments when Smith forced shots when he could have passed.

Smith’s response to Woodson’s coaching lesson was to attempt one shot in 27 minutes against the Boston Celtics on Friday.
