4 New UFC Champs in second half of 2013?

The UFC has some exceptional champions, but there's a chance that four titles could change in the second half of 2013, because there's a boatload of great contenders emerging in various weight classes. Here's the top four odds of new champions being crowned in the last half of 2013.

1. Anderson Silva regaining the UFC middleweight title against Chris Weidman

Chris Weidman pulled off an amazing upset over Anderson Silva; not so much that he won the fight, because many felt he would, but getting a knockout over The Spider was a unbelievable accomplishment. However, for their rematch at UFC 168 in December, Anderson Silva will come in at as a 2 to 1 favorite has a good chance to regain the UFC middleweight strap.

2. Anthony Pettis winning the UFC lightweight title against Ben Henderson

In 2010, Anthony Pettis defeated Benson Henderson to win the WEC lightweight title in the organization's final event before being amalgamated into the UFC. Now Showtime Pettis has a chance to do the same thing again at UFC 164 in August when he takes on Ben Henderson for the UFC lightweight gold. He did it once before and Anthony Pettis is even money to do it again in this fight which is a coinflip situation: 50:50.

3. Junior Dos Santos against Cain Velasquez

Junior Dos Santos defeated Cain Velasquez to win the UFC heavyweight title, and then Cain Velasquez won it back. Now the two fight again in a battle that could really go either way. Once again a 50:50 fight in October at UFC 166. These two could fight a best of seven potentially as they are far and away the best at heavyweight and evenly matched.

4. Johny Hendricks against Georges St-Pierre

GSP's greatest threat to date is Johny Hendricks. That mammoth of a left hand that Hendricks posseses plus his amazing wrestling is a perfect combination to defeat Georges St-Pierre. GSP always rises to the occasion, but Hendricks is going to come in only as a slight 2 to 1 underdog in this contest at UFC 167 in November.
