Is he in as bowler or an allrounder because quite clearly he is not effective as both.And as i said you need that 4th bowler to keep runs in check,bowl tight line and relieve some pressure on main bowlers.Shardul is not capable of doing that.Moreover,Nitish Reddy was bought as an allrounder and he was bowling few overs for the team and if team wanted a specialist 4th bowler than there are 100's of better options than Shardul in India.
