The odds are extremely tight for the UFC 189 main event Saturday. Per Odds Shark, Conor McGregor is the slight favorite to take down Jose Aldo's replacement, Chad Mendes. McGregor's odds are set at 19-20, and Mendes is just behind him at 87-100. Aldo was forced to back out of the much-anticipated battle with McGregor because of a rib injury.
Stylistically, Mendes presents a much different challenge for McGregor than Aldo. While Mendes does have explosive power, he's also a world-class wrestler. That skill set could be the undoing of McGregor.
