Must admit, I rarely hear of basketball poaching or targeting players from other codes, rather the exact opposite.
I see it this way:
Basketball is probably one of the highest skill sport there is in degree of difficulty (team sports I am referring to), because unless you start at a young age and develop that ball handling skill with eyes up, you can't go to the elite level and that is too hard to teach older kids in the view of most coaches.
Throw in all the technical stuff, different shooting positions, angles, defense etc, etc... And you probably get the idea!
Conversely our kids learn many valuable skills and show great aptitude for other sports which they can adapt to with less of a requirement to learn very difficult skills like you need to in hoops.
The result (broadly speaking of course), is that many codes love to pick up an athletic hooper with great vision, the ability to catch and have good hand-eye coordination, excellent reflexes and fitness that they can adapt to their sport, it is an attractive proposition to them, not so easy the other way around IMO...
