Recruiting High Schoolers

It's your job to teach the greatest sport of mankind. You are doing the kids a favor by "recruiting" them. You need all the athletes you can to field the best football team you can. That is your duty, to your school, kids, and parents. If the "team that has been there" has a problem with inner-competition, then they only care about themselves and not the greater good of the program.

How to recruit the "halls"? Age old question, though. Things we have done, was just stop them in the halls and either;
ASK them "WHY AREN'T YOU OUT FOR FOOTBALL!?" - challenge
Encourage them "Hey, Jack, you ever thought about football? We could really use you out there, you'd have a lot of fun...you know 'Jim', right? He's out for football...."
The biggest obstacle kids have in trying a new sport is they just don't know enough about it to form an opinion. Tell them they will be better off because of it, that they can't do without it....what ELSE (worthwhile) are they going to do, anyway?

The REAL Question is....how come this wasn't done in the off-season? THAT's when you recruit.
