It's interesting, the CSA could make the case that after the fitness rules were implemented and they reached the final of the World T20. I do remember thinking in the semi final that, Tazmin Brits not only batted well but took several catches, that Lizelle Lee probably would not have done (based on having seen her field terribly in the past). I still think they would've stood a better chance with DVN coming in to bat in the middle order and as another bowler.
Either way, it's a real shame to lose her from international cricket but at least good that there are options for her to pursue in the WBBL, The Hundred, WCPL, (maybe a WPSL) and sitting on the bench watching RCB be rubbish.
