The role is too much work for a Fleming or Vettori when they can work 6 weeks in India for the same amount. I could see Fleming as the short form coach
The obvious candidate is McMillan for the sake of continuity. He is in the role and its a progression. As long as he keeps the boof factor to a low low low
If Macca takes over, he'd do well to replace himself as batting coach with Matt Bell who is the Whitefern's batting coaching at the moment.
If Scotland let him go - given they (shamefully ICC) didn't qualify for the World Cup, - surely Bradburn is first in line.
