Olson, 25, just finished a 12-game season with the Kansas City Phantoms of the Champions Indoor Football (CIF) league, an arena football league based in the Midwest.
He also spent time with the CIF’s Wichita Force and the Indoor Football League’s Iowa Barnstormers — the same arena team that produced Kurt Warner.
Before his pro career got started, Olson was a career backup in college, spending four seasons at Stanford before transferring as a graduate student to Clemson. He never threw a pass at Stanford and completed one of three passes at Clemson for a loss of 1 yard.
