In his review of American Sports Story: Aaron Hernandez, Lawson calls the new series “a worthwhile examination of a murderer’s motivations” and praises Rivera’s performance. “It is, in many ways, the role of a lifetime, an opportunity to explore extremes of the human experience that Rivera seizes with controlled gusto,” writes Lawson. In conversation with Busis, Rivera, who was part of the first national tour of Hamilton and starred in Steven Spielberg’s West Side Story remake, reveals that he actually played high school football, though he ditched it as his passion for musical theater grew.

“I thought about it really seriously for a little while,” he says in regard to sticking with football. “It’s just a monumental time commitment that made it really difficult to do anything else, and at that time I was starting to get really into singing and performing. I had performed in front of an audience for the first time, like, my sophomore year of high school…. It was something I started to pursue a little bit more seriously, and it just conflicted with football a little bit.”

Getting back into shape was easier said than done for Rivera. He had just three months to transform his body into that of a star NFL tight end after booking the role. “It was just like, you just gotta get as big as you can by April,” he says. With the help of a personal trainer, he was able to pack on the pounds. “I was 185 pounds, and I gained about 30 pounds, which was crazy,” Rivera continues. “I didn’t know that that was naturally possible. It was, like, five days a week in the gym, and I was just eating as much as I could possibly eat.”

Even more arduous than the physical toll was the mental toll of playing someone as notorious as Hernandez. Rivera shares that he had anxiety about taking on the part and found the task at hand “very daunting in the beginning.”

“I’m very motivated by not making a fool of myself,” Rivera says. “I don’t consider myself, like, a controversial person. I don’t want anybody to be offended or feel insulted in any way…. I want it to be truthful, and ultimately my job is to take all the information that I’m given and the resources that are available and paint a picture with that.”
