They've had some good results. 2 titles is pretty good. A nice draw and they can make progress in the open. I think long term they could turn into a spears/Kops-Jones team, not really threatening at slams but capable of beating the top teams. Or they could go there seperate ways. I don't know how Watson/Robson is looking for long term potential or if it's just a Wimbledon/Fed Cup/Olympics pairing.
