I try and focus on posting X's and O's, but this topic has been extremely interesting to me since I was a player. And when I look back on my favorite coaches it was the men that checked all three boxes.
How do you show your players that you care and value them?
There are 3 Primary Sources of Praise.
1) Performance-Based Praise
Ex) Great Run, Great Catch, etc.
This is absorbed by the athlete as "You did this well"
2) Effort-Based Praise
Ex) I see you working, Keep up the effort, etc.
This is absorbed by the athlete as "Your effort matters"
3) Personal Praise
Ex) I'm proud of you, I am proud of who you have become, etc.
This is absorbed by the athlete as "You have inherent value beyond this performance."
Performance and effort-based are important, but they are also the two easiest as you are praising the things that they are doing within the purview of your sport. Finding ways to inform your players that they are more than just athletes can have significant impact on player well-being and overall team culture. If your players feel that they are cared about as people as well as being cared about as players, great things can really happen.
Find ways to make your players know you care about THEM, not just about what they can do.
