The former Scout.com five-star running back put up career highs as a junior when he rushed 197 times for 760 yards and seven touchdowns and had 35 receptions for 328 yards and three touchdowns.
Clemson head coach Dabo Swinney lobbied to keep him around Clemson for one more season, but Harper chose to leave because he felt it was in his best interest to get a jump start on his pro career.
"I sat down with my family and we looked at all the options," he said. "It was the best decision for me and my family."
Harper said his size and athletic ability are appealing to potential NFL teams.
"It's kind of rare that you see a guy at 230 that can run as fast as I can and can make people miss, go through them, over them, around them," he said.
At the Clemson pro day on Thursday, Harper peeled off 40-yard dash times of 4.40 and 4.45.
One of the Tigers' top pass catchers in 2010, Harper's life in the NFL could be extended because of his ability to catch passes.
He's confident that showings at the combine in pro day will help his draft stock.
"That was the whole plan, get over there and open some eyes," Harper said. "A lot of people didn't expect me to come out early, and I did. That was definitely the plan, to get out there, and I did a good job."
Meetings with pro coaches and personnel have gone well, too.
"I've never really gotten in trouble. I never got suspended by the coaches, never had academic integrity [issues]. I've been a pretty good student," Harper said. "They asked me about pass protections, why I'm coming out early—things of that nature."
