The Olympic final is the ultimate example of how Andy should play on grass, some of his shots that day he was hitting seven bells of s*** out of the ball with sublime accuracy, he basically hit through Federer and i think nobody on earth could have beaten him that day.
The best part about that is, he has the memory safely tucked away in his mind and will use it come Wimbledon.
Andy was in the zone in that final and that can be created only once in a while under some specific circumstances. It's almost impossible to be in that zone all the time. That high level focus and dedication is not easy to achieve. Having said that, Nole was able to achieve it almost for a whole year in 2011. Best season in the Open era by a player they say.
If Andy can do this, let's say, a bit more often, I am sure his popularity will increase overnight, but then again, Andy's a very moody player. So that's two things standing in his way.
