However there are players far better than Sachin, and now through IPL some has got identified. During the early days the competence isn't that high which gave him the opportunity to play for a long even if he hasn't performed good at times. Now the scenario is different, if one hasn't performed good in few matches he'll be in the fifteen members but won't get into the playing eleven. Moreover over the years kohli will smash all the records that have been made by Sachin who is prasied as the God of cricket, and in my personal opinion he played for his records than playing for the country.
Are you talking about Don Bradman and Viv Richards, i don't know whether you used to watch cricket for a long time or a recent viewer, IPL is not cricket and you really do not need stamina and patience, just brute force is needed to clear the boundary and everyone with good hand power can do in any pitches around the world now, i guess according to you Gayle and Andre Russel are better than Sachin as they can clear the rope easily
. As said by many above, you cannot compare cricket players of different generation.
Don Bradman was playing without any protection while the bowlers were aiming for their heads and so does Viv Richards, look at their average, no one could compare them with the players we have now.
