#2 Robbie Lawler

Robbie Lawler truly is "Ruthless"

Following one of the most exciting UFC title reigns of all time, Robbie Lawler found himself on the receiving end of a brutal KO loss at the hands of current UFC Welterweight Champion Tyron Woodley. Ever since losing the UFC 170 pound title to Woodley, Lawler has been on a rough streak, so to speak.

However, most experts attribute Lawler's apparent decline to the fact that the countless wars he was involved in over the years, in promotions such as EliteXC, PRIDE, Strikeforce, and the UFC, have finally taken a toll on his body. Well, to be honest, that may very well be the case, especially because his reflexes seemed to have slowed down in recent fights.

Nevertheless, we simply cannot deny the fact that during his prime, Lawler was indeed one of the most violent fighters in all of Mixed Martial Arts. Lawler's boxing skills and heavy hands are what truly made him stand out from the rest of the pack, and his finishes of fighters such as Adlan Amagov, Scott Smith, Melvin Manhoef, and Rory Macdonald, prove just how deadly "Ruthless" Robbie is...
