Never had this one happen - feel

about how I handled in retrospect.
Sit - A inbounding after violation - going long so I bounce the ball to the inbounder... he catches so I turn away to watch screens etc (2 man)
Next thing I know the ball is rolling out of bounds on the sideline - he dropped it and it rolled out.
I blow and give the ball to the other team... I am thinking I should have reset and given the ball back to the inbounder...
