CPL Lickit STKNP v St Lucia Kings at Gros Islet

What was flectcher thinking why did he choose to bowl a young layne and permaul in the powerplay over one of his his best bowlers like hasaranga nortje and shamsi

I was surprised to see Permaul in a T20 team, but observing the moves of Fletcher, he seems to have no plan on how to use his bowlers.
