It is inevitable in sports that human error will become a factor. Passes will be dropped, errors will be made, and open shots will be missed.
But perhaps nothing is quite as infuriating for fans as when calls are blown, or circumstances occur that are so unusual nobody is quite sure how the moment will be resolved.
And thus, controversy ensues, aided by the fact that players, coaches and fans of the team think every call should go their way. Any given game could be littered with controversial moments, one side or the other feeling cheated.
But no nothing evokes as much criticism or passion as the following 25 moments on this slideshow. These games or plays continue to be debated and talked about to this day, the memories still fresh for those who found themselves on the losing end of the controversy.
These are the 25 Most Controversial Moments in Sports.
(Note: I stayed away from moments that were later discovered to be influenced by off-the-field shenanigans. So you won't find anything related to judges being payed off or anything of that nature on this list, such as Roy Jones, Jr. being robbed of gold, or the 2002 Winter Games figure skating scandal.)
