Johnson's deal is worth $1.8 million with a signing bonus of $425,000, while Anderson received a $23,000 signing bonus.
Although, as a rookie Johnson's biggest impact will likely come on special teams, at some point he should compete for a starting job. He's played both free and strong safety while at Florida, meaning the Bears see him as a possible replacement for Mike Green or free agent to be Mike Brown.
Johnson, one of four players from the University of Florida selected by the Bears during the draft, was the first of two fourth-round picks for the Bears this year, selected with the 100th overall pick. The 6-1, 200-pound safety was a three-time all-Southeastern Conference performer during his five-year career with the Gators (1998-2002). He spent the final two-plus years of his career as the Gators starting free safety after beginning his UF career at strong safety, starting 35 of 47 career games played while recording 284 tackles (187 solos) with 15 PDs and nine INTs.
Anderson was on the phone with the Packers talking about an undrafted free agent deal when the Bears took the guard with the second to last pick in the draft 7th round, 261st overall). He has a shot to make the team as a backup, but will have to compete with Terrence Metcalf and veteran Aaron Gibson.
Anderson was a four-year fixture at right guard on the offensive front-line for Pittsburgh (1998-2002), starting 45 of 46 games played. The 6-4, 325 pounder earned all-Big East Conference honors as a senior and was named a freshman all-America.
Defensive end Michael Haynes (1st round, 14th overall), quarterback Rex Grossman (1st, 22nd), cornerback Charles Tillman (2nd, 35th), linebacker Lance Briggs (3rd, 68th), defensive tackle Ian Scott (4th, 116th), wide receiver Bobby Wade (5th, 139th), wide receiver Justin Gage (5th, 143rd) and defensive tackle Tron LaFavor (5th, 171st) are the eight remaining Bears draft choices that have not signed.
