ESPN 'experts' predict the National Football League wins/losses each week. The above chart shows the percentage of their correct guesses and an overall trend, week by week.
The graph shows an interesting trend: the 'experts' get worse as the season progresses. More data would be accumulated each week, giving better indicators as to a team's performance which should result in better predictions. However, this is not the case except for the "Pick 'em" predictions which started worse but trended upwards as the season progressed. In the game of American football, there are a great many variables involved in the outcome of a game, which would contribute to its unpredictability. Perhaps this explains the above phenomenon.
People watch the games for entertainment. If you knew beforehand who was going to win, then why watch the game? In fact, that is exactly the point of watching a game - because you don't know the outcome. Therefore, it is baffling why so many sports networks insist on predicting games - if they ended up correct 100% of the time, nobody would bother to watch, thus shutting down the sports networks!
