Where you can, avoid using simple judgmental terms like ‘good’ and ‘bad’ as they immediately turn players off.   Successful / unsuccessful, complete / incomplete,  positive / negative  mean the same thing but are not quite as judgmental.   Why is this?   Well take a pass for example,  Player 7 may play a perfectly good ball to Player 11 who doesn’t go for it with any conviction and is beaten to the ball.   This should be recorded against player 7 as a ‘pass incomplete’ as opposed to a ‘bad pass’.   Ever given a player feedback and realised later that you were really praising him, when they thought you were knocking his confidence?
