He is the chairman of RPG Group not RPSG group which owned and operated RPS in IPL and ATK in ISL.. RPSG is owned by his brother not him and he isn't involved in anyway with that company.
Similarly, DC is co-owned by one of the Jindals, that hasn't stopped from his brother Naveen to pick up the tender ITTs...
That being said, I can certain that Adani and RPSG group will bid to their necks to get the teams... Glazer's involvement is somewhat unexpected, they will do anything if they want it badly, just look at Man Utd takeover itself as the example.. Let's see.
