What exactly do you mean by that? It is a mid range replacement ( or will be ) for the MIG-21 line.
Understanding that requirements for the IAF has changed, there is no room for such an inferior fighter. Either it IS a replacement for Mig-21 (unlikely) or MRCA is the replacement for the Mig-21 (likely). IAF would prefer anything but LCA thats for sure, and the recent statements by IAF Air Cheif Marshal clearly suggests that IAF is now insuring that it has minimum of the type of the aircrafts to clear the logistics and maintenance problems in her air force.
However, inducting for the sake of inducting is another thing, and no way clears up for the operational requirement for the induction of fighters in any air force.
