They are a better metric than forum posters because the odds they determine are fully objective as bookies are trying to create odds which would create a profit for them. And to answer your question, 0. How many slams since Fed won his last slam, btw?
Not to mention that the matches are not played on paper... And also, those odds are released 6 months before the event even takes place... So one would reasonably expect them to change with the betters. Additionally, what if Nadal gets hurt or has a terrible 2017 season? Wouldn't they then change the odds to make him an even longer shot to win? As if the bookmakers can't or won't change the odds overnight...
