Video: MMA's top 10 welterweights ahead of UFC 170's key matchups

Check out the countdown of the top 10 welterweights in the latest USA TODAY Sports/MMAjunkie MMA Power Rankings.

The list, which still sees former UFC welterweight champion Georges St-Pierre in the top slot, could feature some big movement in the coming weeks. Rory MacDonald meets Demian Maia in a big fight at this weekend’s UFC 170 event, Dong Hyun Kim faces John Hathaway at next week’s The Ultimate Fighter: China Finale, and Johny Hendricks vs. Robbie Lawler and Carlos Condit vs. Tyron Woodley will bring real meaning to March’s UFC 171 fight card, crowning not only a new UFC welterweight champion but perhaps the next No. 1 contender, as well.

Check out the top 10 above, or check out this week’s full USA TODAY Sports/MMAjunkie MMA Power Rankings, which includes the top 15 in each weight class.
