"It's important for a guy like myself who isn't as highly touted coming into the draft," Charles said. "People are questioning size, speed, agility, things like that. Having a good day today is really going to help out."
Charles did indeed enjoy a successful day of workouts and drills, starting with the 40-yard dash. The Oshkosh, Wis. native checked in at 4.62 seconds in the 40, with some stopwatches showing times as low as 4.60.
"I was really hoping to get a 4.59 and maybe shock the world," Charles said. "It certainly beats a 4.8, which everybody probably expected."
He also turned in times of 4.18 seconds in the pro agility and 6.96 seconds in the three-cone drill. A two-time state high jump champion in high school, Charles posted a vertical leap of 36 inches Wednesday. He believes he erased some doubts about his athletic ability.
"I think that was the biggest question," Charles said, "Just more or less my athleticism."
Size has never been a question for Charles, who was measured at 6-foot-7 and weighed in at 217.5 pounds.
Charles also took part in individual receiving drills, running routes along with running back Anthony Davis and Winona State wide receiver Chris Samp. Charles believes he made a positive impression on the NFL scouts present.
"I think they saw a lot of explosiveness for a guy my size," Charles said. "Quickness, running routes, how I come in and out of my breaks. They were able to see my hands in person. I think I answered some questions."
