One of the things that makes sports so exciting is the fact that an upset can happen at any time. Upsets are the lifeblood of sports, with the potential for any team to beat another. For neutral fans, this is great. For sports bettors, though, this can be a blessing or a curse. No bettor wants to be on the wrong end of an upset, nor do they want to back an upset in a game where one does not take place. But there are some signs that bettors can use to get an idea as to when an upset might take place. Injuries are such a game changer in the world of sports, as key players being unable to compete due to injury can have a massive impact on a team’s chances of winning a game. And those injuries can open up the possibility of an upset in the right situations.
