Lots of "ifs" there, Tianyi. I'm not disagreeing with you, but my own perspective is that I could get equal or better players in my own state without having to reach too far.
The key to keep in mind is budget. I would think the $1700 to scout the state of Texas isn't quite as big a deal to D1 teams. For me, that initial cost often limits what else I can look at. If I were a D3 team in the state, that's over half of one scholarship allowance.
