The amount of time and money he has spent in getting himself into the ODI squad or the T20 squad it was evident that those articles would come out. He got his first official century in an ODI in the last match against South Africa. Ishan Kishan, SKY, and Samson all of the three debuted in 2021, look at the stats of Ishan Kishan and then compare them with Sanju Samson's stats. He debuted long back in 2015 in the T20 format with a ton after that he has been out of touch in both ODI and T20 formats. He has been unable to cement his position in the Indian team because of his performance with the bat. I guess this century would give him some confidence and will help him get himself into the probable list of players for India.
He only played 16 matches in the 8 years that tells why he don't have stats like other players because some players reached 50 mark stats in less than two years but he is just unlucky to be in that position and he is having batting avg of 55 which is extraordinary though. He is still under 30 if I am not wrong, so if one of the senior players retires, then he may get more chances if he keeps his batting skills sharpen.
