Junior dos Santos may smile like an innocent child, but inside the Octagon, he's a dangerous man. The UFC heavyweight champion will be making his second title defense in the main event of UFC 155 against the man he took the belt from, Cain Velasquez.
Although dos Santos is primarily known for his boxing, and rightfully so, the Brazilian has a number of tools at his disposal when defending his belt. We've seen JDS utilize some kicks, wrestling and have heard about his jiu-jitsu game from a number of people in the MMA world.
He will need all of those tools and perhaps a bit of luck in order to defend his title against the dangerous Velasquez at UFC 155.
