Clowney and North Carolina tight end Eric Ebron, another first-round prospect, wanted to get a jump on the scouting process.
Although they aren't playing in the Senior Bowl because they're juniors, they came to the all-star game for a series of meetings with NFL teams.
The athletic 6-foot-6, 275-pounder is a candidate to become the Houston Texans' top overall pick in May.
"It's very valuable to put a face with a name, and be out here watching the guys," Clowney told The Baltimore Sun. "It's something to experience."
Clowney is one of the most physically gifted players in the draft in recent years.
As a sophomore, he recorded 13 sacks, 23 tackles for losses and was named the Southeastern Conference Defensive Player of the Year and a consensus All-American.
Clowney plans to conduct a full workout at the combine and put on a show, in his words.
"I plan on doing everything," said Clowney, whose 40-yard dash times reportedly range between 4.4 to 4.5 seconds. "I plan on doing everything. It's all about competing and I'm a competitor."
Clowney became an instant star following all of the television replays of his crushing highlight hit on Michigan running back Vincent Smith during the Outback Bowl.
During his final season at South Carolina, Clowney dealt with several minor injuries and his production dipped to 35 tackles and three sacks.
Now, Clowney is expected to face questions from NFL teams about why his junior season didn't match his stellar sophomore year.
Clowney had a big smile on his face as he talked about his upcoming NFL opportunities.
"It's very special," Clowney said. "I'm just going to take advantage of it and train and get better and just compete. I'm gifted and my work ethic is also going to set me apart."
