Watch sports for long enough and become a fan of a team or a sport and you'll have seen it time and again.
An athlete bursts on the scene early in their career only for their career to fizzle out or not live up to the expectations and hype surrounding them.

But it didn't.
Instead, Hall and Joseph went on to make history and became the first ever Penn State freshmen to capture national titles and solidified themselves in the annals of Penn State history.
