Make no mistake about it: This is one of the closest matchups that the UFC has put together in recent memory. Ultimately, whoever dictates the location of the action will have his arm raised.
Typically, Rafael dos Anjos won't look to put a fight on the canvas unless his opponent is trying to put the Brazilian on his back. If Evan Dunham is willing to stand and bang (he will be), dos Anjos is more inclined to oblige.
However, dos Anjos is on a three-fight winning streak, which is largely thanks to his wrestling. It's hard to imagine that he would turn his back on a game plan that has been so successful as of late.
Dunham is dangerous from the clinch, which is where dos Anjos will look to score takedowns.The Brazilian will score a time or two, but he won't keep top position long enough to steal rounds.
Between the damage scored from close quarters and the high volume of strikes that he will land during standup exchanges, if he keeps it standing, this is Dunham's fight to lose.
Prediction: Evan Dunham defeats Rafael dos Anjos via unanimous decision.
