Yeah, I don't see Sock cracking the top 10 unless it is a particularly weak year. That said, players of similar ability are able to sneak in every once in awhile. He isn't that far away from players like Tommy Robredo, Mikhail Youzhny Juan Monaco, Nicolas Almagro, and Gilles Simon, all of whom have been in the top 10. And don't forget that Janko Tipsarevic finished two years in a row in the top 10. But I see him as being in a slightly lower category than those guys, more in the Kohlschreiber/Seppi group. He'll vie for best American player with Isner, Johnson, and Querrey for the next year or so until Fritz, Tiafoe, Kozlov, and maybe Donaldson all pass them.
