Co-Director of Munciana Volleyball Club, Mike Lingenfelter, talks about different styles of coaches, distinguishing coaches into two categories: Thermostats and thermometers.
Thermostats are coaches who enter a room, practice or game and dictate the environment and culture based on what they feel is needed for success. These coaches are often a bit more fiery and vocal, and often need a counterpart or assistant coach that can be more adaptable to the situation.
Other coaches are what he refers to as "thermometer" coaches, meaning they'll monitor the environment of the room and adjust their mood and temperament based on the mood of the room. Those coaches need a co-coach or a player that can provide the fire and serve as the "thermostat" of the team.
