The year is 2012, and the world of tennis is exciting as ever. Who do you think will be the dominant 5 players in that year? I think Murray and Del Potro will stay at the top 5. Federer, I'm not sure he'll even play by then, and I think Cilic will also become a top 5 player. Nadal is a tough call at the moment with his injurries and style of play. Djokovic is a good possibility.
