It may have been the impacts. Naturally, the only thing the article is concerned with is whether there's any water on Mars.

"...theoretical modeling of the polar wander of Mars showed that the rotation axis of Mars could have moved by as much as 70 degrees within a geologically short time period in response to the emplacement of Tharsis mass [Spada et al., 1996]. The theoretical modeling also demonstrated the crucial effects of the mantle viscosity and the thickness of the rigid lithosphere on the polar wander."

What tipped Mars off its' then axis? It might be that all the planets flop around unless they have a large moon to provide stability.
