#4 Rajasthan Royals being the feeder club
Feeder club is one that sells all their players to the other clubs, basically, acts as an academy to the other clubs.
Anyone who follows football will know how good Southampton would have been had they managed to keep all their players instead of feeding them to their rival clubs. Gareth Bale, Alex-Oxlade Chamberlain, Theo Walcott, Sadio Mane, Dejan Lovren, Adam Lallana etc. have left Southampton and moved to other clubs in Britain. These examples are evident enough to term Southampton a feeder club in EPL.
When it comes to the IPL, Rajasthan Royals were doing the role of Southampton, ie. producing some young talents and then selling all of them. Now, the Royals have just made themselves available for the IPL after missing the last two seasons due to a suspension. However, in the past, they have had produced talents like Ravindra Jadeja, Yusuf Pathan (yes, seriously), Naman Ojha, Kevon Cooper, James Faulkner, Sanju Samson, Ajinkya Rahane etc.
Instead of sending them to the auction pool, the Royals might have sold the players had there been a transfer window like they have in Football.
