I really enjoy Davis Cup, irrespective of who is playing for GB. Always have, the first I remember was GB v Italy at Wimbledon back in '76.
Did Andy burst into tears when being interviewed last July because it was Davis Cup or because he was playing at Braehead? Who knows. Did he play last year just to qualify for the Olympics? Possibly. It's his career and his choice.
He had to play last year, whether he wanted to or not, in order to qualify for the Olympics.
