Honestly Roger will certainly win more slams but you have to be delusionnal to think he will have another shot at the calendar Grand Slam. And this in my opinion, speaks volume on Laver's achievement. OK it was a different time etc. but still, to put up together 4 slam vicories in 12 months including clay and grass, the 2 opposite surfaces, is a huge achievement. If Roger wasn't able to make it (he was 2 sets away from it in 2006 and 2007...), that has to be very tough. I don't see him do this one with more slam contenders and time taking its toll. Your thoughts ?
