I stopped overly talking and critiquing. This is something I started working on at the beginning of summer and its helped so much. I felt like because I know the practice plan and purpose of drills so well that I always had to 'show' that but often, less talking, more observing helps the players actually figure out the solutions to the problem you give them. Realizing that its not about giving them all the answers , but its about having them work through it and you help them along the way.
