"It was definitely a surprise. I did not really follow Chris Lynn's injury. I did not know how serious it was," the former Delhi Daredevils and Rajasthan Royals spinner said.
"Be it spin or pace if you can can add some valuable runs at No 6, 7 or 8 it helps any team. Then you do all three of the game -- bat, ball and field," the 32-year-old said.
"These days if you are an out and out bowler, be it spin or pace, you have to be at your best. You need to do really good to just be a bowler in the game. Then you got to be a decent fielder. So you have to do at least two of the three.
Botha also said the Eden track would assist spin which has been the core strength of the defending champions.
"This one helps the spinners definitely. If you see the Knight Riders line-up they have really gone for the spinners that obviously tells you that it does assist the spinners. As the tournament goes on, it starts to spin a bit more. Chennai normally spins a bit and they have got quite a few spinners and also a bit in Wankhede," he said.
