Is J.R. Smith upset with his playing time? Is he concerned that he won't get enough shots in the Knicks' offense? Does he just need more time to work on his free throws? These are just some of the possible reasons why Smith would run onto the court and join in on the 8-year-olds' basketball game during halftime of the Knicks-Pistons game Monday.
The more likely reason is that J.R. Smith is just a crazy person.
