I love this quote from former Yankees Manager Joe Girardi, Show kids your belief in them regardless of how they perform. It's easy as a coach to praise great performances. The less obvious praise is to demonstrate to the less heralded player why you depend on their contribution to make the team excel.
"There has never been a soccer game where one player has defeated another team singlehandedly for up to 90 minutes", Former SYSA President Dave Jolie. Identify the contributions of every player because they all play a role, whether this is obvious or not to their teammates. This isn't about getting everyone a trophy though, make them earn their praise and feedback. This is one of the great joys of coaching, seeing a player put the work in and achieve whatever it is they set out to do. One seemingly forgettable throw in, played well, can make the difference in a game.
This other coach sums it up better than I can...and with more credentials.
