This is just the time he was an OC, not counting stops where he was just the QB coach.

 

2006: St. Louis, 10th in points scored with Bulger, Jackson, Holt, Bruce, Klopfenstein

2007: St. Louis, 28th in points scored with Bulger(missed 6 games)/Frerotte/Berlin, Jackson(missed 6 games), Holt, Bruce,  Klopfenstein

2009: Tampa Bay, 30th in points scored with Freeman®, Cadillac, Antonio Bryant/Sroughter/Stovall, Winslow Jr.

2010: Tampa Bay, 20th in points scored with Freeman, Blount, M. Williams, Winslow Jr

2011: Tampa Bay, 27th in points scored with Freeman, Blount, M. Williams, Winslow Jr

2014: Oakland, 31st in points scored with Carr, Murray/DMC, J. Jones, Holmes, Rivera

 

Seeing how most believe the most important thing is whether Blake Bortles improves or not I think it's worth noting that in his work with young QB's Olson hasn't been bad. 

 

Josh Freeman's first three years in the league with Olson as OC

 

2009: Pct. 54.5 Yds 1,855 Avg 6.4 TD 10 INT 18

2010: Pct. 61.4 Yds 3,451 Avg 7.28 TD 25 INT 6

2011: Pct. 62.8 Yds 3,592 Avg 6.52 TD 16 INT 22

 

Derek Carr's rookie season 

 

Pct. 58.1 Yds 3,270 Avg 5.5 TD 21 INT 12

 

Obviously there is a lot of things that go into a teams success offensively so take from this whatever you want. Unlike many people here I don't pretend to know whether Olson will work out or not but I just wanted to provide some additional information to the discussion.
