I had to go back 3 pages to find the last non-4 player mentioned. It was Monfils! lol
Monfils plays to way behind the baseline to have any chance of a top 10 career!
He used to, but made some big improvements and changes to his game in the latter half of last year, and ended the year ranked at a career-high 14th. He has a grand total of 40 points to defend before Monte Carlo, he will almost certainly enter the top-10 at some point. Whether he can consistently stay there....probably not next year, but with the game he possesses (huge serve, big forehand, great athleticism) he should be in the top-10 with an injury-free year (he'll get one eventually) and his head screwed on as it has been the latter half of this season.
