he never gets mentioned but you gotta put Eddie Robinson on that list. The guy was a monster, he had some world bench press record as a teen and he was a big shot in the arm wrastlin circuit plus he was f'n huge. He lost all his momentum with the WBF but he was gonna be the next big thing there for awhile.
Shane Dimora was awsome as a teen he turned pro, he won like 3 national shows in one year but he ended up tearing a pec and was never the same but if you look at pics of him at 19..it's just incredible.
