1. Sack machine

Rousseau got after the quarterback in 2019. The defensive end led the ACC with 15.5 sacks in his final season at Miami, which also tied for second in a single season in program history. His 15.5 sacks were a close second to Ohio State's Chase Young who led the nation with 16.5 in 2019. Rousseau's career-high came against Florida State when he racked up four sacks.

2. Huge upside?

Rousseau has only played in 15 collegiate games over his two seasons at Miami. The edge also opted out in 2020 due to COVID-19, but his 2019 season proved he has a high ceiling. The edge rusher finished his 2019 campaign with 54 tackles, 19.5 tackles for loss and seven quarterback hurries.

During an interview with InsideTheU, Rousseau explained he picked up the edge position quickly during his true freshman season before getting injured.

"I just kept getting better and better," Rousseau said of his first season at Miami. "Scrimmages came and the first one I got like four sacks and I was like, 'Man this is like taking candy from a baby.' Obviously it wasn't that easy, but things were just clicking for me. My hard work was paying off. I was learning the scheme. I was getting better in my techniques. I just kept on getting better scrimmage by scrimmage."

3. All-around athlete

The defensive end wasn't always a defensive end. Rousseau played a variety of positions in high school including wide receiver, safety and defensive end. During his senior season at Champagnat Catholic, Rousseau tallied 10 sacks and 80 tackles. He caught 28 passes for 467 yards and scored nine touchdowns in 2016.

4. Graduated early

He's serious on the field and in the classroom. Rousseau didn't need four years to get through high school because he graduated from Champagnat Catholic early. Champagnat School Director Isabel Alonso said she is proud of how hard he worked at school.

"Greg's the first kid at our school who has ever graduated early," Alonso told The Athletic. "I gave him the biggest challenge I thought I could ever give a kid. There's not supposed to be enough time in the day to practice and train and do a full year's worth of school in one semester. But Greg didn't sleep."

"He spent every free moment he had making sure he got everything done. He went to class from 7 to 2, practiced from 3 to 7, then went home and did everything he had to do with his online classes — English, Pre-Calculus, Economics and Physics — on weekends and at night. Not only did he not miss a single practice the whole time, but he finished his last exam the day before he enrolled at the University of Miami."

5. Learned football from Madden 2005

Before Rousseau started playing football, he was introduced to the video game Madden NFL.

"My brother bought that game when I was a little kid," Rousseau told InsideTheU. "I just fell in love with it. I was like, 'This is so fun. This is awesome.' I started learning all the players, Mike Vick, Steve Smith, Ray Lewis, Ed Reed. All the players that were in the league, I started learning them. I just fell in love with the sport."

Rousseau said he started playing football when he was around seven or eight years old. He had a head start on the game thanks to Madden.

"Pretty much before I started playing in pads I already knew what a post route was, a Cover-2, a running back counter, all from playing the game all day long and learning the different coverages," Rousseau shared. "Ever since then, I've been a football junkie."
