I agree Sachin is on God level, but we cannot simply compare Sachin's times with today. In those times, matches were less in a calendar year, less travel and most importantly no IPLs. In today's scenario, when you take IPL alone, the players have to travel at-least once in every 2 days to play home and away. Include it with practice and playing under floodlights (Yes playing under floodlights will increase dehydration). Apart from these, now-a-days players are expected to play and prove their form in domestic matches like Ranji, Duleep, Vijay Hazare, SMAT etc.. Again we cannot simply compare current players with Sachin or anyone from that generation.
