No Nadal is a horrible thing for us Rafa fans, Sakuraba! 

 I'd rather see no Novak, Murray or Roger instead 

 To me, Rafa's game is the most entertaining one.
I agree, Novak is a contender. I'll give him that even if he hasnt looked as solid as previous years in the pre- US Open tournaments. He's also probably extremely happy with no Nadal this year. Last 2 Us Open final between those guys have been classics, and it's a shame we dont get a chance for another this year 

. But hey, i still hope we get some great tennis regardless of who ends up in the final.
I think Roger is looking good, and yeah he must be thrilled with no Rafa, not only cause he doesnt run into the chance of having to play him, but it guarantees him he wouldnt meet Novak until the final. Is he consistent enough to win another Us Open? I honestly dont know. But he does have a better chance this year for sure. 
I was away on vacation last week, and they had the tennis channel available. I had a blast watching some older guys tournament (i dont remember the name, sorry lol), and got the chance to see Agassi play vs Courier (Andre won!) and then vs Blake to win. The old guy still has some game in him! Would have been awesome to see Agassi vs Sampras, but Pete didnt play it. Not sure if he plays much in the old pros tourneys. Isner is the most solid american guy atm, but for some reason despite having that killer serve he just cant break through. Maybe the crowd can inspire him in the Us Open? who knows.
