A two-year starter at free safety for the Golden bears, the 23-year-old Johnson finished his collegiate career with 107 tackles along with three interceptions. In 2009, Johnson recorded a career-high 52 tackles to lead all Bears defensive backs.
A pro personnel source told Scout.com that Johnson, a non-NFL Combine invitee, put together a very strong pro day back in March. Johnson, who posted an eye-popping 43-inch vertical leap, also posted a 40-yard dash time in the 4.3 range, the source said. A strong vertical leap, in the mind of scouts, shows explosion through the hips. The source also notes Johnson does not play up to his listed size and is quite raw, which explains why he wasn't drafted. However, while no other teams put in a waiver claim for the athletic safety, he remains an intriguing prospect.
Johnson, if he has a strong training camp, could push for the team's fourth safety job.
The Henderson, NV, native was a college teammate of Eagles wide receiver DeSean Jackson at Cal.
