Tennis rankings work on a 12 month rolling period. So today's ranking are from all the points you accumulated over the past 12 months.How did Federer drop below guys that didn't even compete at this tournament? (Del Potro) Also fell behind Anderson who got bundled out earlier in the tournament. How does that work?
At least you might see some other guys challenging within 18 months. This might be the last year of the real dominance for Djokovic and Nadal. You'd expect them to split the Grand Slams in 2018, only injury would tell me otherwise. However in 12 months you will have Tisipas and a few others like Coric challenging. Think Coric may break out at the US Open and make a huge run (just a gut feel)I hope the season is interesting this year, I don't want to see the same top 2 players dominating again.
