Yes, there are several head coaches at the DI-FBS level that never played (and there are some coaches at the NFL level). You can certainly coach at the high school level.
There are many ways one can become a football coach. It also depends on what level of coaching is desired. One could volunteer as a youth coach, or help coach a high school team. With the right connections, one could get a job helping a small college football team and then work their way up into the coaching ranks. Also, being a graduate assistant for the football team while in college is a way to get a start. Former players sometimes have the best chances because they understand the job a little better and have connections from their playing days.
