Not a bad effort by the looks of things, he's still very much a newbie at this level.
He won't have come across many players like Dustin Brown before, at any level. All part of the learning curve.
Agreed. Jay was giving up 130 places and a decade of experience, 6-4 6-4 not a hiding by any means and plenty to work on no doubt.
This true and part pf the learning curve is coming up against...unorthodox players and how to play them. Like your servebots (Isner, Karlovic), serve and volleys (elder Zverev), showmen (Monfils, Kygrios and Brown) and everyone in between.
Is Neal clearly a better option than Ken these days?
On the face it it is mainly because he has played more with other partners that he is higher ranked than Ken. Although rankings anyway are a less reliable indicator than singles for who would be best since they have partners and need to form a Davis Cup partnership that they will at best have rarely formed before. Well, unless they play Neal & Ken together. I've been quite impressed with the little I've seen of Neal but not seen enough to make any real judgement.
I wonder too if Joe in time might come into the equation.
I saw the Skupskis in a couple of games at Wimbledon and Ken seemed to be carrying Neal the whole time - I presume Neal is better than he showed but Ken should have been higher than he's got
