2015 Year-end Ranking Predictions

The tennis season is just one day away for main draw singles action. That means it is time for me to make my predictions on what the year-end top 100 will be for the upcoming season. These are the most difficult predictions to make, because predicting the rankings 52 weeks in advance means I have nothing to base these predictions on other than my own expectations for 2015.

This is my fourth year making these predictions, and it seems to get harder every year, particularly because of the parity in tennis over the last year or two with teenagers breaking through and the Big Four's stranglehold on the tour slipping.

These are how my predictions did in the previous three years.
2012
Mean difference between predicted and actual ranking: 31.10
Perfect Predictions: 6
2013
Mean difference between predicted and actual ranking: 31.56
Perfect Predictions: 3
2014
Mean difference between predicted and actual ranking: 31.49
Perfect Predictions: 1

And these are my predictions for the year-end top 100 of 2015

I was off on average by just 25.76 spots, which was by far a record for me, but I only had two picks exactly correct, which were Novak Djokovic and Kei Nishikori.
