Smith had 15 sacks for 115 yards in losses, 19 tackles for loss for minus 124 yards, forced four fumbles and recovered two fumbles as a senior.
The 6-foot-3, 252-pound Smith played in the Senior Bowl and was moved to the linebacker position. Since then he's been working at defensive end and linebacker and his stock has been soaring in recent weeks.
"I thought I did everything I needed to do," Smith said after Pro Day. "I thought me doing all of the defensive line stuff was great and me doing all of the linebacker stuff was great.
"Whatever teams wants at that time of the draft, I don't mind. If I go as a defensive end that's great, or a linebacker that's fine."
Smith is now projected as a second/third-round pick by NFLDraftScout.com and is rated as the fifth-best defensive end in the draft. One scout told Cardinal Authority on Monday that Smith "will go off the board pretty fast after the second round ends."
After the Pro Day, Smith said he met with the Indianapolis Colts and has a workout scheduled for tomorrow with the Atlanta Falcons.
"There's a lot to like there," one scout said, noting he figures Smith a late second-round pick.
Smith said he feels like since the combine that he has "really improved" on his skills, including the linebacker position.
"At the combine, I think I only did three linebacker drills and so the scouts didn't really get to see me open my hips," he said. "I think I showed them today that I can do it."
Smith had the fifth-fastest 40-yard dash time - a 4.68 seconds - and the eight-best broad jump of the defensive linemen at the NFL scouting combine. He also had a vertical jump of 35 inches.
"I always tell teams that I first bring a winning attitude and a winning attitude in the locker room," he said. "I am going to be someone you can count on. I want to be one of those guys who becomes a Pro Bowler, I want to be one of those players who becomes a legend."
