Let's talk about the domestic Indian players who were talented but couldn't represent India or couldn't represent India for long due to any reason.
First name that comes to mind is
"Ashish Winston Zaidi from U.P."
@cricketwallah

Another is: @amolmuzumdar11. Brilliant domestic record but to no avail.

Another Domestic Stalwart Devendra Bundela @DevendraBundel4. 9654 first class runs but couldn't make it to the Indian Team in 90s.

Wasim Jaffer with 19000 plus First class runs, represented India in 31 tests with a double (212) against West Indies. Wished he could have played more for India @WasimJaffer14

8317 runs, Rashmi Ranjan Parida is one player who was highly respected in the Indian cricket. @cricketaakash in his book described him as "He is one of the best players of spin bowling I have come across..when I see someone like tht at the top of his game, I count my blessings"
