Gilbert played 15 times, with a 10-5 record, so I'm not sure what conspiracy Joe is trying to get at? Spadea has only played once 0-1, which given his typical position on the tour sounds about right.
Let's face it, P-Mac has to not only think of the current team, but who's going to lead the USA in the future. I don't think Spadea, at age 29, will fit into that equation. Like it or not, Roddick, Fish, Blake, Ginepri, and the Bryan Bro's are the future of USA tennis. At least for today. IMO, the only way you deviate from these guys is if a new player come up, or Agassi decides he wants to play.
