[Sully]

I've been coaching HS for four years. I knew I wanted to teach and coach, so I thought that if I volunteered while I was still in school, it'd help. It did help a ton, just not getting a teaching job (there just aren't any).
However, I highly recommend doing it. You'll find pretty quickly that in the grand scheme of things you don't know a lot about football, but if you are willing to work, you'll learn fast. I played (VERY) little college ball, and with as much football as I'd been around, thought I knew my shit... But found out quickly I had (and have) a ton to learn.
I volunteered for a year, then after proving my passion and work-ethic, was a paid coach. I've coached OL, DL, LBs, DBs, and been a DC and OC at the freshman level.

It's not for everyone. I've worked with coaches who set records in college and were horrible, and guys with little playing experience who were great.

If you want to do this, let me know. I've got tons of advice, if you want it.

But don't you dare do it to relive your HS days, so you can pretend you are one of the boys again. I've seen too many of those guys.
