I wholeheartedly agree, but...
Changing bands because the pianist tends to rush seems a bit drastic, don't you think? I've found it immensely useful to play with people who have strong tendencies to either push or pull the time. It makes me focus on keeping the boat going steadily, and I've noticed that my timing and my awareness of timing has benefited from it quite a lot. And it really makes me appreciate the people who do play in the pocket with me!
