There is a difference between a captive audience and an audience held captive.
Coaches any drill can be good or bad depending on what you do with it. Make sure your drills are teaching skills that can be applied to the game. Change your drills so that your players are not bored when they come to practice. I know it’s better to be razor sharp at a few things then mediocre a many things, but that does not mean you can’t teach the skills you want to emphasize in different ways and in different drills. Give your players new challenges in your teaching environment. It’s been my experience players actually want to work hard for you. They are bored when they are not working hard.
Find a job you love and you'll never work a day in your life. – Confucius
Coaches give your players a job they’ll love.
