I would emphasis one more point. Promote the positive benefits of track and field to other coaches outside your sport. Let football coaches know how you plan to train their linemen to be explosive throwers and how this will benefit them on the football field. Let the skill position guys know what your sprint workouts will do for them on the field as well. If they see that you know what you’re doing and respect the needs of ‘their’ athletes, they will do a lot to encourage their athletes to participate in track and field.
