The continental 'S' feature which eventua the process of Oceanic crust development (and still does) accentuates the rotational mechanism and involves the actual coastlines of those continents and the ancient roots of their shape -

The power to generate a 26 mile spherical deviation between equatorial and polar diameters via differential rotation across latitudes is certainly many magnitudes greater than what is needed to move the thin fractured crust. What it takes to move men to look at this connection between evolutionary geology and rotational dynamics is quite another story.
