I've thought about this lately myself. But with the Giants being defending champs, and basically having a good team that's hurting with injuries right now, I don't see them giving up the season just yet, too early.
Remember how we played early on, before the injuries. We were getting timely hits, pulling out gritty (ugh, that word!) wins in late innings despite some shaky starting pitching, and certainly looked to be headed for the playoffs at least.
I wouldn't mind a re-tool of sorts, but too early to throw the towel in now.
