I thought of it before to gamble on sports betting site and bet only on those with good odds for higher chance of winning, but there are cases when even if the odds are good, your enemy is bad luck or an upset. Look at the case of Manny and Thurman, Manny is the underdog at first, then tables turned when the fight draws near.
That's part of sportsbetting, the odds aren't really the sole basis for each match's victory. For the case of Pacman-Thurman.
Yes, Manny was the underdog but it suddenly changed prior to the date of the match. It's not a sure win whether the odds are good for high chance it's better to include some analysis too before betting.
