The signing of Matt Gutierrez on Wednesday did little to satisfy the Chicago Bears' need for a veteran back-up to quarterback Jay Cutler. Though Gutierrez is entering his fourth season in the NFL, he's joined his third team and has attempted just two passes. (Both were completions)

Sean Jensen of the Chicago Sun-Times reports that in addition to trying to sign a veteran--John McCown, Trent Green, Damon Huard, and Todd Collins all turned down offers--the Bears have "casually explored" trade options to find an experienced back-up.

Who the Bears explored trades with is unknown, but there are several possibilities.

Jon Kitna (Dallas), J.T. O'Sullivan (Cincinnati), Dan Orlovsky (Houston), and Drew Stanton (Detroit) played in Mike Martz's offensive system with the Detroit Lions in 2007. Considering that the Bears were unwilling to guarantee any money to the veterans who declined their offers, base salaries for Kitna ($2M) and O'Sullivan ($1.3M) are likely a bit out of the Bears' price range.

Orlovsky started 7 games for the 2008 Lions, but with the departure this off-season of Rex Grossman, he is now the top back-up to Matt Schaub.

One option that makes sense on paper for the Bears is Seattle Seahawks third-string quarterback J.P. Losman, an experienced veteran with a big arm and a league minimum base salaries for 2010 and 2011. Losman was believed to be even, if not ahead of Charlie Whitehurst is the battle for the #2 spot behind starter Matt Hasselbeck, but Whitehurst's strong performance in the pre-season opener may have widened that gap.

A potential hang-up for the Seahawks trading Losman is that they face the Chicago Bears and New York Giants, the NFL's other QB-needy franchise, during the regular season.
