RDA has a pretty aggressive straight forward muay thai attack, powerful leg kicks and a right hand. He has not bad wrestling, but tries to muscle it a lot, against Diaz he showed a heavy top game (taking in Diaz' lack of being prepared). But, unfortunately for Dos Anjos, I don't see anything that he excels in that Pettis doesn't, he is well rounded, but so is Pettis, but he has a big advantage in striking and his bottom game has improved a lot, so has his wrestling defence. Then there is the striking defence and footwork... Who do you think takes this? What round and what finish/decision? I think Pettis will take it by a head kick in the second round. I honestly don't see RDA giving Pettis too much problems, but Khabib will be back soon!
