I think the man's at the pinnacle of every achievement that there is to be had. He has broken all records ( barring one first class domestic cricket one ), and has stamped his authority on the game. Time to walk away? I would say yes, if only not to try and make a comeback like MSC. That would ruin it for me atleast. He can walk away after that one last explosive, signature style century and Ill give him a standing ovation in my living room.... The Gods need rest too you see. Whats your dig on it?
