Novak will get to 21. It's not that I want him to, because my favorite of the Big Three has always been Roger. But Roger yielded TBE status a long time ago to both Novak and Rafa. TBH... between Novak and Rafa I'd rather it be Novak who takes over the mantle. He may be a bit boorish at times (and a McEnroe wannabe with all the racket smashing)... but he's good on ALL surfaces. I refuse to acknowledge a mega-clay-specialist as TBE. Rafa's #3. But Novak is still young, and it's just a matter of time. As far as the young'uns... it was bound to happen at some point. It may seem these guys have come out of nowhere... but that's just the way tennis is. As for the female side of things, it's good to see some new blood up there as well. With Serena now out of the picture due to age, the field is wide open for some of these upcoming young ladies to take over. There doesn't seem to be a Serena in there just yet, though.
