Preparation
When giving feedback, it is best to be fast and focused. The sooner a performer has a chance to incorporate the feedback, the better. Long, meandering speeches are highly ineffective. Instead, seek to use as few words as possible. Develop of vocabulary of terms and phrases that the entire team understands. Plan your feedback in advance, rather than making it up as you go. Take notes during practices and games, being sure to focus on the most important aspects of play. Yes, there's always more to correct, but trying to correct it all ensures that you'll correct almost none of it. Check out the video (1:17) below to see an excellent example of a coach using crisp, focused feedback to improve the level of play.
