Most of the big sports now have some degree of instant replay being used in an effort to get more calls correct. In order to avoid endless games, the big sports have implemented a challenge system, where coaches can officially question calls and ask for a review. I see this as great progress in sports, as I hate to see games turn on incorrect rulings. Some of the rules about how the challenges can be used, though, make me wonder if the goal is really to get things right or if it’s just to appease the fans a little bit. A good example of this happened in the game between the Tampa Bay Rays and the Toronto Blue Jays on Saturday.
