A possibility yes, but not an certainty as some people have you believe. Because you rule out unpredictability. Could you honestly have predicted years ago that Juventus would win the serie A undefeated after having been relegated to the second division? Sports is always unpredictable, and you can never say what will happen. Bookies, TV and such had you believe that Chelsea had no chance after being down against Napoli 3 to 1. Or even worse no chance against the best in history, Barcelona. Unpredictability is the name of the game! People who preaches you otherwise, then it just shows that these people don't know nothing about this sport!
