Is this worth my time?

I've talked with a coach who is friend of mine, he has collected several videos and guides on coaching different methods, (example: Pass coverage, route running, "coaching defense", "coaching offense") just many different guides and ways coaches teach players about football. He said I could watch/read them if I thought it would help me in my officiating...(insult maybe !?) Anyways, I guess it wouldnt hurt knowing a little bit, but was curious if anyone else has ever used these coaching guides in helping with their officiating
