The betting line has dropped for the UFC heavyweight title fight between champion Junior dos Santos and former champ Cain Velasquez that is expected to take place at UFC 152, and JDS is a slight favorite early. The only book offering a line at the moment is Bookmaker. Here's what they have (via BestFightOdds):
The line actually opened at -135/+105 on Friday night but has moved a tiny bit since then. Personally, I find it a bit surprising that JDS is such a slight favorite despite a 65-second knockout of Velasquez in their first bout at UFC on Fox 1 last November. Dos Santos is coming off a second-round knockout of Frank Mir while Cain stopped Antonio Silva in the first round, both at UFC 146.
If you think JDS has the advantage, I'd recommend you bet on him right now. You're not going to get a better price than that.
