Doubtful. Gus mainly landed jabs, and Jones landed approximately twice as many power strikes to the head. Not to mention that Gus was the one that was rocked and seeing double, after all.
Jones having a busted lip and as I already said generally looking more flustered when being hit exaggerated peoples perception of how much damage he sustained.
At any rate, it was a close fight, and Gus winning wouldn't have been that controversial going by the 10 point must system (round 2 and 3 could have gone either way). Neither would a draw.
Albeit, as in the GSP- Hendricks fight, we would then yet again see how flawed the scoring system is. Jones came the closest to winning by stoppage, and had completely taken over the fight at the end. In that sense, he is the rightful winner.
