The Bears will interview Greg Olson for the vacant quarterbacks/ passing game coordinator later today, according to league sources.
Olson provides extensive experience, as an offensive coordinator with the Tampa Bay Buccaneers and the St. Louis Rams. In St. Louis, he worked under Scott Linehan, who current Bears offensive coordinator Mike Tice developed in Minnesota.
Olson has worked with some impressive quarterbacks, including Drew Brees at Purdue. Other quarterbacks he's worked with include Jeff Garcia, Marc Bulger and Josh Freeman.
Olson's first NFL job was as the quarterbacks coach of the Bears in 2003 under Dick Jauron.
In Tampa, he started as the quarterbacks coach but he was promoted to offensive coordinator before the 2009 season.
That season, Freeman finished as the sixth-rated quarterback in the NFL with 25 touchdowns and only six interceptions.
