It seems that you have been interested in boxing for a long time and have experience in analyzing upcoming events. If you have no doubt that Garcia will win, then why not take advantage of this? I mean, bet on it.
It depends on the odds. Even someone likes to bet on his Favorite, if the odds aren't that interesting, it's riskier to bet on his.
As an example, can you handle the risks of placing a bet for $100 when in return you will get only around $10-$20?
Maybe yes since you think it's a sure win but what if in the event of loss which we can't take out the possibility that it can also happen.
