But Hamlin, who hurt his hamstring, said he started feeling better early last week and decided he was going to suck it up and make the best of it. It's a good thing he did because it appears he quite possibly helped his status for April's NFL Draft.
"Hopefully, I have moved myself up a little bit," he said.
He must have done something right because scouts from Houston, Dallas, Miami and Cincinnati all approached him Tuesday and talked to him about how he could fit in their system. He plans to try and meet with each of them again in the coming weeks.
Hamlin has already spoken to Seattle, New England, San Diego, Chicago, Pittsburgh and the New York Jets.
In all, there were 25 teams in attendance to watch more than 20 former Clemson players workout in hopes of trying to improve their stock in the draft or maybe earn an invitation for a free agent tryout after the draft.
Hamlin, who only did position drills, hopes the three-hour session moved him up the draft board.
"I got to the point where I just sucked it up and did as much as I could today," he said.
Coming into the day, most teams had the 6-foot-1, 202-pound safety in the top five of the third round, while just a few had him going late third or early fourth.
Hamlin himself feels he could hear his name called in the second round and no later than the third on April 25.
"Things went pretty well today," he said. "My main thing was to try and do as much as I could on the field until (the hamstring) started bothering me again."
Hamlin's hamstring really did not hurt anything he was doing at Clemson because he had already planned not to run or lift in the event after putting up well enough numbers at the NFL Combine in Indianapolis last month. At the combine, he ran a 4.57 in the 40, which he felt was good enough and comparable enough to other safeties that he did not have to prove anything there.

As for the hamstring injury, Hamlin said his agent, Jimmy Sexton, who also represents current Miami Dolphin and former Clemson standout Phillip Merling, alerted the scouts beforehand that Hamlin had tweaked his hamstring so they knew what was going on.
Hamlin said that was a good move because a lot of scouts came up to him Tuesday and told him not to worry about his hamstring and to make sure it gets plenty of rest.
"They said I should just try and get better," he said. "They said because I did it in training it does not really look negative on me. Everybody said don't worry about it and to just try to get healthy."
What scouts say they like about Hamlin is his instincts, his ability to make plays, his anticipation, his hands and his ability to make tackles.
Some still question his speed and size, but Hamlin hopes he has put most of those worries to rest after Tuesday.
"They always say that I'm a smart player and they like the things they have seen on film," he said.
And it seems like they are starting to like the things they are seeing in these workouts as well.
