Mikey Garcia has been viewed as a potential star since he was a developing prospect. As he has reached the championship level, he's seemed to turn it up a notch and now has to be considered a potential pound-for-pound threat.
But to establish that kind of reputation, he'll likely have to move up another weight class or two from super featherweight, where he has campaigned of late.
In the modern era, climbing weight classes has become a status symbol for elite fighters. The proliferation of alphabet-soup titles makes it tougher to lock down a single division, and advances in sports medicine and the existence of so many half weight classes make it easier to climb.
The fighters on this list are all talented young stars. Their careers will be well-served by moving up.
