There ain't nothing much technical about amateur wrestling. Most amateur wrestlers only have a handful of techniques that they practise to perfection, plus brute strength and speed. There may be some exceptions like Buvaisar Saitiev. You can turn most amateur guys into good pro wrestlers because they have excellent athleticism and mental strength, but amateur stuff doesn't translate well into wrestling because you need more than a double leg and a suplex. Dan Severn pretty much flopped in wrestling for that reason.
