good prospect from one of the best programs in the nation is a bad thing.

jt isn't wrong. If a kid looks like a three star from a place like Skyline, Carroll, Union, Jenks, etc., it doesn't hurt to throw him an offer and gain a commitment.
There is something to be said for taking kids from programs like that. One, they already practice and compete at a high level, so you are more likely to know what you're going to get, and they're going to be more prepared for big time college football. Two, there is a chance that they may be friends/cousins/tight with some better player on that roster in this class or the next class. Or if you want to entice someone from that school to visit later on, you can pair them up on a visit with that player and hopefully enhance the quality of the visit and connection with the school.
There are also other positives like creating a good rapport with the high school's coaches (if you treat their kid right), which may help get you in the door later, etc.
All things being equal, if you're going to take a high two-star or low-three star, go do it from a powerhouse.
