The entire top 10 are all very skilled yet they all have different strengths and weaknesses. Demian Maia can outgrapple almost the entire division but he could not take down All American wrestler Tyron Woodley. Stephen Thompson can outstrike Rory for a decision but he can't land anything significant on Woodley. Woodley almost finished Wonderboy multiple times. Rory Mac can't solve the riddle with Wonderboy but he can beat Maia and Woodley with his jab and takedown defense. His jab and TDD does not help him much with Wonderboy however. Robbie Lawler can beat Rory Mac with his power and ferocity and has proven it twice but Robbie's worst matchup is Woodley. Robbie had to worry about Tyron's takedown and got caught with an overhand right. Rory>Woodley>Lawler>Rory Wonderboy>Rory>Woodley>Wonderboy Robbie>Rory>Woodley>Robbie Woodley>Wonderboy>Rory>Woodley>Maia Also if you are one of those that think Condit beat Robbie then this equation would make sense: Maia>Condit>Robbie>Rory>Woodley>Maia And if you think Cowboy beat Robbie: Cowboy>Robbie>Rory>Maia>Jorge>Cowboy Its like there is no true number one because everyone has a bad matchup.
