Receiver Craphonso Thorpe led the charge with an "unofficial" handheld time of 4.25, showing his teammates and others he's recovering rather nicely from last season's shattered leg.
Linebacker Ernie Sims, who was looking to become the team's top athlete following Michael Boulware's recent dominance, also turned heads with a 4.39.
Plenty of others also were pleased with their testing efforts. Include linebacker Buster Davis in that mix, though he also was quick to add there was plenty of room for improvement.
Davis said he clocked a 4.5 40. He also had a 33-inch vertical jump, 4.22 pro agility (shuttle) and 10-foot broad jump.
Davis, a redshirt sophomore from Daytona Beach Mainland, was all smiles after finishing his 40-yard run.
"You have to actually train for this -- it's all technique," Davis said and grinned.
"This kind of shows you what raw ability you have. It wasn't bad. It wasn't bad -- but it wasn't acceptable. When it comes down to that (NFL) combine, that's when it (40-yard run) counts (laughing). This right here doesn't count at all. This just sees where you are at right now. I am not bad. I am in a lot better shape. It's going to be a good time this season."
Davis wants to be part of those good times, too. Following early frustrations, Davis has made a number of positive changes the past year. He has lost nearly 20 pounds, dropping from 254 to 236. His upper body is more defined, his middle smaller.
"I decreased my body fat around 6 percent," Davis said. "I am leaner. I had to cut that body fat down, make my core a little harder so I can hit more. That's where the power is. I had to drop the weight. I had to."
Davis' want-to also is burning.
He's currently backing up Sam McGrew at middle linebacker, though this preseason battle expects to be one of the team's most spirited.
Davis' improvements on the field have been noticeable as well. He fought off blocks better during spring drills and also was quicker filling the hole. Davis says he also feels comfortable in linebackers coach Kevin Steele's scheme.
Buster remains confident in his ability, but also understands the bottom line is production.
"I have everything going for me right now," Davis said.
"All this (40-yard dash) is for the reporters and the coaches to see where you are right now. I am on pace. I am on pace."
