Jones vs. Rua was probably the most one-sided fight ever. It was several rounds of total domination and destruction.
People are revising history now and claiming Rua, as well as Rampage, Machida, and Rashad were "shot" when Jones fought them. Not true -- they were all at or near their pinnacle, and Jones pushed them down that hill. Those four guys had cleaned out the Light Heavyweight division. In the 3 years prior to fighting Jones, those 4 guys had a combined total of 5 losses -- all to each other!
Starting with the Bader fight, another crazy domination (of an undefeated fighter), those 5 fights in a row are the likes of which we won't see again in terms of quality of opposition and domination of that opposition, all in just over a year's time.
That said, Jones turned out to be a shithole person more or less, and a PED cheater.
Some people want to downplay his accomplishments, others want to ignore his shortcomings. But you can't deny what he did, either in the octagon or out of the octagon, or hiding under it.
