Shane Watson was signed by Royal Challengers Bangalore in 2016. He also managed RCB in the few matches Virat Kohli missed in 2017.
He failed to make an impression, though, and only managed to score 250 runs in 24 games over the course of both seasons.
Quinton de Kock was purchased by RCB for Rs 2.8 crore back in 2018. He had already made a name for himself as one of the top wicketkeeper hitters in the white-ball era.
He didn't play for long enough because Brendon McCullum was already on the team. The left-hander only participated in eight games and managed to score 201 runs.
KL Rahul, a batsman for Karnataka, was performing admirably when he first entered the IPL. In the domestic circuit, he scored lots of runs.
He only managed 20 runs in the IPL's inaugural season, though, and Sunrisers Hyderabad later bought him. In 2016, he went back to Bangalore.
The right-hander had a respectable season, scoring 397 runs with four fifty-pluses.
He was, however, discharged after missing time in 2017 due to a shoulder injury. Kings XI Punjab spent INR 11 crore to choose him in 2018, and this decision paid off.
