If there was ever 'code smell', it's when you see "x = y; // verbose way of saying sets x to y". And this is exactly your example - a verbose description of "$.resize.delay = 16;" If renaming variables and functions in this case doesn't make you feel better, I don't see why a comment would.
But yes... of course comments are important and needed in some cases, which I admit. However when they do, as other posters here have mentioned, it's usually annotating why, not how/what. I can't think of many reasons why it's not a bad sign if you find yourself explaining how something works - the only one that comes to mind is with hand-optimized code.
