I re-watched his fight with Rob and his fights with Kelvin and Silva. Even in the Whittaker fight, Adensanya was getting tagged pretty good. Rob became over-confident at the end of the 1st round and ran into a perfect counter. Overall tho, Whittaker was finding his mark on the much taller Adensanya for most of the first and a good part of the 2nd. Kelvin and 56 year old Anderson were getting good shots on him as well. Technically, I think Adensanya is way superior to Costa.......but Costa has a chin and way more pop than Whittaker so it could get interesting. Jon Jones would make Adensanya look foolish, people need to slow their roll on that.
