New York Giants unrestricted free agent quarterback David Carr will visit the 49ers this weekend, according to Mike Garafolo of the Star-Ledger. Carr's also expected to be in the mix with the Cardinals, so it's likely that his time with the Giants has come to a close. We'll soon find out how much faith the Giants have in former Oklahoma/Sam Houston quarterback Rhett Bomar.
Keep in mind that the Redskins just released backup quarterback Todd Collins, who led Washington to the playoffs in '08. And there's always the Jeff Garcia option, although he's never really fancied himself as a backup. Mark Brunell had a great influence in the Saints' locker room. He's be a good option -- as long as he wasn't called upon to play more than a game or two.
I think you'd feel a lot safer with Collins or Garcia. Then you could try to get Bomar ready for the No. 2 job. Here are some other candidates off the league's official unrestricted free-agent list: Panthers QB Josh McCown, Lions QB Patrick Ramsey, Texans QB Rex Grossman (likely headed to Redskins because of Kyle Shanahan), Dolphins QB Chad Pennington (Hmmm...), Steelers QB Charlie Batch, Rams QB Kyle Boller.
Another possibility is former Bills quarterback J.P. Losman.
