Bucannon ran the 40-yard dash in 4.49 seconds at the NFL scouting combine, bench pressed 225 pounds 19 times and had a 10-6 broad jump and 36.5-inch vertical leap.
Bucannon has a reputation as a hard-hitting tackler and is regarded as a rising draft prospect. He has over 10 official visits scheduled and has conducted three private workouts, including with the Philadelphia Eagles.
Bucannon trained for months before the NFL scouting combine at Disney Wide World of Sports with noted speed trainer Tom Shaw as well as retired former Ravens starting cornerback Fabian Washington.
"One thing that stuck out to me about Deone is he's a worker," Washington said in a telephone interview. "He always wanted to work. I'm like, 'Dude, it's time to go,' and he would say, 'Help me out with one more drill.' That stuck out. He's one of those guys who never wants to leave the field. I could see him working out for the Ravens. He fits their mold as a guy who wants to work and is a hard-nosed football player.
"He's like a human crash dummy. All he wants to do is tackle. When he first got there, he was really, really stiff. We have worked a lot on his hip flexibility. He knows that's what he really needs to work on. The biggest thing is his work ethic. He wants to learn. He's not afraid to ask questions. He shuts his mouth and listens."
Bucannon was a finalist for the Jim Thorpe Award last season and a second-team All-Pac-12 selection.
He led the Pac-12 with 109 tackles last season, intercepted five passes and forced three fumbles. He was a four-year starter and a three-time captain.
For his career, Bucannon has 379 tackles and 14 interceptions.
"Watching his highlight tape, I can see him playing for the Ravens," Washington said. "When I saw that the Ravens were going to work him out, I knew he was a Ravens type of guy. He's sideline to sideline. He's really good with the ball in the air. He can track the ball and he's tough."
