Demetrious Johnson has emerged as the world's best flyweight with a win over Joseph Benavidez, but there are a number of 125-pound fighters looking to take the belt that hangs around his waist.
At UFC on FX 6, Johnson's first challenger will likely be determined in a bout between John Dodson and UFC newcomer Jussier da Silva.
Dodson is looking to become the first The Ultimate Fighter contestant to win a UFC championship since Rashad Evans. Meanwhile, Da Silva has won five straight fights and vacated his Shooto belt for a chance to pursue UFC gold.
Only one can earn the title shot against Johnson, so let's take a look at where the advantages lie for Dodson and Da Silva heading into this matchup.
