I think you need to do some research yourself. The Adams guys were all over the boards when ACU was winning NCAA titles w/ Nico and the Riftians.
The bottom line is that it's not breaking any rules recruiting from out of the country, but you have to admit most schools in DII aren't able to do this (don't have near the resources). Also, by recruiting foreign pre-made talent, you're getting kids/men that are faster than most American kids who'd consider DII as an option. Admit this, an American kid who'd run as fast as Huffer, Theofile, Cragg, Mwei, etc... (before the went to Adams), wouldn't touch a DII school with a 10 foot pole. By recruiting Internationals you're landing high level DI recruits that you couldn't get from the U.S HS system.
