By rephrasing the passage, it can be divided into:
A common belief or idea: "international coaches emphasizing on technique and relying on a strict training regimen are overdoing their job"
consideration/reason for the common belief: the professional sportsmen lack neither the skill nor the expertise
conclusion on the common belief: the role of a coach must be more of a people manager and a facilitator --> boldface 1
consideration/reason (1) against the common belief: no sportsperson is flawless in technique ...
consideration/reason (2) against the common belief: lack of technical advancements may outmode tomorrow, a competitive sportsperson today --> boldface 2
Author's main conclusion: those arguing for softer coaching at the highest level must rethink

from the above understanding,
the first boldface is not the main conclusion (A) or a support for it (E). Besides, it is not used to oppose the main conclusion (D), but the other way around is. In other words, it is opposed by the main conclusion of the author (B,C).
the second bold face is not opposing the main conclusion (A) and is not the main conclusion (C), but is a consideration (not an evidence D ) that supports the main conclusion (B,E)

Only B represented both boldfaces correctly
