Canelo is the most favorite in this match, as it shown that his odds in most bookies is around 1.25-1.3 in average. If you believe that Jacobs can do something unexpected then you will get odds around 3.75
It worth to bet on Jacob with small amount but with high odds if you are so sure about it. Obviously it will be high risk for you but it can be a high return.
For obvious reasons, that only advantage that Daniel Jacobs is height, and everything else favors Canelo here so it will be a big risk to put money on Jacobs.
Alvarez is in his prime, however, I'm not totally sold on his win against GGG though. It is still a questionable win for me. But again Jacobs, I don't see him losing the fight.
