Yes, atleast Sunil Gavaskar and Harsh Bhogle know Hindi. VVS doesn't even speak Hindi properly, pronounces many words wrong. No idea why they put him there.The hindi commentary team on most channels have commentators who don't naturally speak hindi. People like Sunil Gavaskar, VVS, Harsha Bhogle etc. have always been English commentators. Forcing them to speak hindi deteriorates the quality.
