For anybody thinking about bringing David Carr back here as a backup, well, he's still in San Francisco. But it sounds like he's only holding on by a hair.
The San Jose Mercury News reported that Mike Singletary was none too happy with Carr's 7-for-17, 53-yard passing effort against the Raiders Saturday night. Whether he's on his way out, though, is another story. And it's unlikely he'd be cut before Saturday's deadline, if even then. But if he does get whacked, he'd be an ideal choice to bring back here, since he's the only guy out there who knows the system.
He'd probably come in as a third-stringer, though, since Bomar has done the work to become the primary backup. And let's face it, if Manning goes down early, the Giants' season will be basically wrecked, anyway.
