DUBAI: Brendon McCullum has "no negative bone in his body" but whether he succeeds in his new job as head coach of England Test team, to an extent, could depend on how well he adapts to coaching in red-ball cricket after managing T20 franchises, feels Dinesh Karthik.
Karthik teamed up with McCullum during their stint together in the IPL with the Kolkata Knight Riders -- McCullum and Karthik were coach and captain of the franchise respectively in the 2019 season.
