4. David Miller
At the end of 2015, Miller had the stats of 1319 runs with average of 42.55 and strike-rate of 147.54. However since 2016, the numbers of the South African middle-order batsman has drastically dropped. He scored only 531 runs from 30 games at an average of 22.12.
Moreover his strike-rate has also alarmingly dropped. As a result Miller might not find a regular place in the squad. Thus he can now be thought as a power player option. Miller can strike the ball cleanly and clear the boundary with ease. Thus this role will bring the best out of him.
5. Jasprit Bumrah
This Indian pacer is currently the best bowler across all formats. It is mainly through T20 and IPL that Bumrah became famous. His ability to bowl yorkers at will and change of variation is what deceives the batsman. However many might argue of using Bumrah as a power player option.
This is because Bumrah is usually a full four overs bowler. However he only bowls one over in the powerplay and the other three overs in the death. So if Mumbai Indians can find someone to do the job upfront, Bumrah can bowl all his four overs at the end. This could be more lethal and tough for the opposition.
