       Hi, I’m Michael Jones. Before we do anything, I want to tell all of you something about howmy practices will be conducted. I think we all have a tremendous amount of work to do if wewant to win the championship this year. As we all know, we’ve lost most of our top players, andthe competition this year will be tougher than ever. So, this year we’ll be having both fieldpractices and classroom practices. I guarantee that these practices together will make us winners.Let me tell you about how the two kinds of sessions will be different. In these important fieldpractices, we’ll be putting in all our plays for the year, as well as working on the basics of strengthand endurance training. I’ll supervise these workouts closely, and you’ll do exactly what I say.During the classroom practices, however, you’ll only be working with your teammates. In yoursmall groups you’ll be going over sports psychology and exercises designed to build team spirits.There’s lots of room for your ideas here.
