Usually people don't try to steal the ball from me when I drive, but when they do, I take advantage of it. Sometimes, when I drive I grip the ball between my hand and arm, or I palm it, and I bring it halfway behind my back. They think I'm going to throw a behind the back pass and stop running to try to deflect it.

Or if they players are smaller than you, like you mentioned, I would lay up like this

I wouldn't necessarily go reverse, but I'd keep the ball above my head.
If you want a foul, cradle the ball with two hands and let them hack at you.
