Teaching a specific skill
In introduces the area of training or instruction.
Coach commonly combines with in for skills or subjects and for teams or events. By and with usually have different grammatical roles.
Use coach in for areas of training or skills: coach employees in communication. Use coach for a team, event, or purpose: coach for the Olympics. At may refer to a location. By usually introduces the coach in passive structures, and with often introduces tools or methods rather than a direct verb pattern.
