Nadal dominated little tournaments? LOL Nice try troll but winning 2/4 majors and 5 Masters titles isn't under the category of dominating little tournaments.
To have a realistic discussion about this, people are forgetting that Nadal didn't play Doha, AO, Miami, Halle and crashed out in R1 at Wimbledon.
There's a TON of points up for grabs there, in fact it's:
250 + 2000 + 1000 + 250 + 1990 = 5490 possible points.
Now obviously he's not going to win all of those, but if he makes it deep enough at AO, WIM and Miami that should make up for not winning as many Masters next year as he has this year.
His biggest battle will be defending Canada, Cinci and US Open points. That's the realistic time frame where he could lose the ranking.
