I’m an academic turned sports writer from Raipur, India, specializing in the NFL, MMA, and tennis at The Playoffs. I previously wrote for Sportskeeda and hold a B.A. and M.A. in History. My journey into sports media began far from the field, rooted in the arts and sciences. Funny enough, I didn’t grow up a sports fan; I used to see it all as just noise. But a fateful writing job introduced me to the world of sports, and what began as a gig quickly became a passion. I understood those voices aren’t noise; they’re emotions of true sports fans, and now I am one of them, writing with the same energy I once questioned.
