When I say talent, I mean pure ability in terms of skill and ring IQ, not his ability as a fighter. As you said, his outside problems are hindering his development as a prize-fighter. Has bags of talents, but not focused enough to reach his full potential at the moment.
Of the ones that haven't won a title yet, it's between Jaron Ennis and Vergil Ortiz IMO, both were good amateurs, have great technique, speed, power, a mean streak and they fight at the same weight class as well.
