I've got some time to kill, so I'll do some analysis of the seeds, and which ones I'd like Novak to play against.
25-32 seeds (possible 3rd round opponents)
Weakest seed of the group: Starace. He has only 2 hard-court wins in 2007--neither against a top 150 player.
Would make an interesting matach: Safin. Novak still has not had the chance to avenge Safin's dominating win at the 2005 Australian.
It's 2005. Novak just starts his taste of ATP tour and Safin was playing the best tournament of his life other than 2000 USO.
13-16 seeds (possible 4th round opponents)
Weakest seed of the group: Gasquet. Despite a career high ranking in July, Gasquet is only 2-8 against the current top 20 this year (0-5) on hard courts.
Would make an interesting matach: Canas. If Canas had not had to come through qualifying at Miami, he might have made the final there a little closer.
I think Hewitt will be a more difficult one. Cañas is at a slump right now.
5-8 seeds (possible QF opponents)
Weakest seed of the group: Robredo. Only 8-15 against current top 50 since Australian Open. 1-7 on hard courts.
Would make an interesting matach: Blake. Blake and Novak have never played. Can Novak neutralize Blake's power as effectively as Federer does?
I think Novak can neutralize Blake's power. But he needs to serve well. Blake is very good in returning 2nd serve.
