Personalities are different as to how they react. A lot come in cocky and already know everything. Some are intimidated and need to build confidence. Common method is to tear them down and then build them up. However you don't want them to evaluate as they are playing but react automatically with what they have been taught. That is a confidence Trent has had since day one. Smith looked like the other end of the spectrum and seldom looked comfortable. Not a coach but in business I never found micromanaging to be very successful and you only want to rant on mistakes when they don't understand why it was a mistake. Once they understand why they already feel bad and you need to go to the positives. They need to be having fun to build an attitude and play freely IMO.
