Smith, a 6-foot-2, 265-pound rising junior, excelled during the many drills, with Northwestern defensive line coach Marty Long getting an up-close look.
"It went great," Smith said of the camp. "There was a lot of competition out there. Coaches seemed really interested in me. I loved being there."
During the camp, Smith took part in one-on-one drills and the physical board drill. His goal was to demonstrate the intensity NU coaches hoped to see.
The drills were run at the speed of Northwestern's practices -- a high-temp, physical style. Smith embraced that.
"It is non-stop movement, everything is with a sense of urgency," he said. "That's what I liked about it."
At the end of the camp, Smith was stopped by Coach Long, who wanted to have a brief conversation.
"Coach Long told me he likes me and he's going to keep an eye out on me," Smith said.
Northwestern had expressed interest in Smith prior to the camp. Smith's performance last week was just icing on the cake.
Smith is thrilled for the continued interest from the Wildcats and hopes it continues going forward.
"It's great, especially coming from a Big Ten program like Northwestern," said Smith. "I'm very interested in the school. Their academic programs are one of the best in the nation."
Thus far, Smith has received offers from Illinois, Indiana, Notre Dame, Purdue and others and recruiting interest from Northwestern, Florida, Georgia Tech, Michigan, Michigan State, Ohio State, Stanford, Texas and Vanderbilt.
The thought of playing Big Ten football intrigues Smith, who was born and raised in the city of Chicago, the home of Northwestern and heart of Big Ten country.
"I've watched the Big Ten since I was a little kid," he said. "It's an honor to receive Big Ten interest, especially from a program close to where I live and one known well throughout the nation."
