Neither. I was watching, and I think that the question took Mr Henman by surprise: it appeared that he wanted to be supportive, but not over confident. Hence the long pause, whilst he tried to frame an inoffensive but not over-optimistic reply. He acknowledged that "Top 20 realistic, Top 10 a stretch" may be seen by Mr Evans as motivational, though.
I'm not sure which is worse, that sort of desperate-to-be-honest reply or the "of course number one is the aspiration for everyone" claptrap that you get from some.
