His loss to Aldo was completely legitimate. Mendes probably wouldn't have gotten finished at the end of the round but he wasn't keep aldo down and he had nothing for him in the second.
Mendes has improved a lot though I do agree, still don't know how much of a shot he has though.
Like you say he probably wouldn't of been finished at the end of the first, but the 2nd round is all just speculation, anything can happen in an mma fight. I also agree that Aldo would of gone on to win, probably convincingly. But the messy last min robbed Aldo of a legitimate win.
How can you claim it to be legitimate based on a speculation of what Aldo "would" of done.
