To be in the top 10, you have to be very consistant with your results and be healthy enough to play a full season. For as many knocks as there are on Roddick, the guy manages to stay healthy, usually goes deep into most tournaments, and wins a few titles every year... which is why he is a perennial top 10 ranked player.
Pim-Pim is certainly capable of beating top 10 opponents, but what I question is whether he will ever be able to play a full schedule again without being hurt, or have any consistant stretches of high level play. To note, from January of '04 until July of '05 (which was the best stretch of his career, and where he very briefly cracked the top 10), he only won 3 titles and got past the 4th round of a major once... all the while losing in the 1st round 15 times. (By contrast, Roddick has only lost in the 1st round 29 times in his entire career, going back to 1999, and he has only had 8 1st round losses since the beginning of 2005.)
