I think in sports, sometimes you've got to let go of the data and trust your experience and instincts to make judgements. There's professionals who do that. American sport (NFL, NBA, MLB) drafts kids out of high school, college and forces teams to make decisions to select someone No.1 and pay them millions. There's a reason why they had LeBron James on the Sports Illustrated cover at the age of 17.
It's the same with Jaiswal. Every instinct I have from close to 40 years of watching cricket tell me I'm watching a future all-time great when I watch him bat. I can wait for years of proof to confirm this belief but my instincts don't need that proof.
That's fine, and I don't mind your thinking.
For me I like to wait until a sample size is established. That doesn't mean a player has to play 20 years for me to make a judgment usually even 2 to 3 years is enough or heck maybe even 1 year at times.
But this guy hasn't even made an odi debut and has barely any list A and fc experience. Has played t20 most of his life and barely has any overseas international experience.
It's a massively bold claim to say with confidence that he'll be > the likes of saeed, Ganguly, Yuvi, Sanga or whoever comes his way when all these players have achieved while Jaiswal is just an infant atm with massive talent.
Longetivity + impact + memorable innings all these things count
For example Saeed Anwar, To this date not a single pakistani batter has more odi centuries then him despite the fact that he played in a much harder era and against top teams then the nepal and west indies club bowling Babar stat padded against. Similarly he has the highest odi score for his era which wasn't broken until years and years later and even then he still has the 2nd highest odi score achieved by a pakiatani batter.
Yuvi was MVP of an entire 2011 tournament. He's the true hero of that tournament considering sachin wasn't a factor in the final only a factor in semi final and group stages and yuvi overall was the best player that day + in the tournament in general.
I cam go on and on about ganguly and Sanga like how sanga has 4 back to back centuries against England, has one heck of a test record, 2nd highest odi run getter of all time etc etc.
Jaiswal is an infant and has nothing atm? No tournament victories or any thing noteworthy yet? He just started?
