What's with this draw nonsense?
I don't understand why a draw is needed as it defeats the purpose of seeding. The object of seeding is to create a merit draw enabling the two players adjudged to be best to meet in the final and to avoid the rest of the top thirty-two players eliminating each other in the earlier rounds. In the round of thirty-two and assuming the seeds all win, number 1 should play number 32, number 2 should play number 31 and so on until number 16 plays number 17. The number 1 seed should play the first match of each round.
In this tournament, Nadal is nominally seeded number 1 but Federer is the actual number 1. Federer plays first and Federer will enjoy the resulting extra day of rest over Nadal. Also, Federer is drawn against weaker opposition than Nadal. For example, in the round of eight, Federer faced the number 8 seed while Nadal will play the number 6 seed.
Scrap the draw and stick with the seeding plan.
