Jump Ball from behind player

[All_Heart]

In Game 6 of the Cleveland vs Washington series, Danny Crawford called a jump ball where Lebron James had both arms wrapped around Daniel's back and was holding the ball. If you didn't see the play it's okay because everyone has seen this happen at some point. A1 is holding the ball and B1 wraps both arms around A1 from behind and tries to get a jump ball called. I call this the bear hug foul. I was shocked to see Crawford call this a jump ball and was hoping someone would give some insight into why he called it this way.
