3 'Assistant' Coaches appointed, alongside First Team Coach (Robinson) and Senior Coach - Bowling (Barnes). In other words, what appears a demotion for Frost (who is now just designated 'Lead Batting Coach') and promotions for Westwood (now 'Assistant First Team Coach') & Sheikh ('Second Team Coach' - assisted by Frost for Batting & Andrew Sutton for Bowling).

No mention of Trotty's 'Batting Consultant' role.
