I've never used a crate to train any dog I've owned, including Flash. It took more effort and a longer time to potty train him than it had with any other dog I've owned, but it was successful. He's also never been destructive of furniture, clothing, etc., but I think that in large part, that's because such behavior was never tolerated and alternative behaviors were encouraged and rewarded.
I agree with Mikey in that many people use the crate as a crutch.
