Action expresses priorities.
As coaches we have all had to deal with the player who talks a good game. He will say all the right things. Then when in the game his actions betray him. TEAM play is ignored in favor of ME play. There is a general refusal to embrace a role within the team concept and the player will act as if the team is present to serve his purposes.
A good video session with players such as this can often go a long way towards rectifying the situation. The player may decide to conform to the team philosophy or the player may seek greener pastures elsewhere if he is stubborn and resistant to learning.
Actions often resound and resonate louder and longer than mere words.
Actions definitely provide a view into a players priorities.
