Why would it matter where his feet are if he's dropped the ball from his hands already? The only violation would be carrying to ball in his hands outside of the area...
Could throw it three feet in front of himself if he wanted to and wouldn't matter as long as his hands weren't touching the ball outside the area. I mean, he's allowed to drop the ball and kick it off the ground, roll it out, throw it out... so why would it matter that his feet stay in the box? Everything is about the hands.
