"So far, so good," Osei said and smiled after clocking a 4.52 (handheld) in the 40-yard dash.
Osei, a 6-foot, 200-pound redshirt senior from nearby North Florida Christian, is looking to end his collegiate career on a positive note.
He's also hoping for a little luck after being plagued by injuries since his arrival in 2000.
"I just worked so hard this past summer -- I've never worked this hard," Osei said.
"Fortunately, I was injury-free so I could just work as hard as I wanted to. I didn't have to slow down or anything. That really helped me out a lot."
Osei, who is listed behind fellow senior Jerome Carter at rover, has been slowed by a broken hand, a torn Achilles tendon that required surgery and a bothersome hamstring over the years.
Knock on wood, but he finally feels as good as new.
"I worked hard the past summers but it seemed like I was always slowed down my something," Osei said.
"My hamstring, my Achilles. I never could seem to go full speed. This summer I was able to go full speed on everything I did, so that helped me.
"The best I've ever felt? Right now (laughing). The last time before that was probably in high school. It's good to feel like that right now and I am just hoping it carries through the season."
Osei, like many, believes the Seminoles have the talent to make it a memorable season. FSU's secondary is expected to help set the tone and, of course, should be tested immediately in its Atlantic Coast Conference opener against Miami.
"We have a lot of talent, we have a lot of experience. We should do well this year," Osei said.
