What is the potential for Julio Cesar Chavez Jr.?

Right now he is 21 years old and already 35-0 with 28 KO's, he hasnt fought anyone good, but he has a great record and is so young and is knockin people out, how good could this could be, hes young, strong, and undefeated he is right now a light middleweight maybe becoming a middleweight in a year, can he become a champion or is he fighting bums and winning and has no serious championship potential?
