I've seen so many options....
Mike Kafka, Palko, Charlie batch, and even Brian Hoyer.
First crack: Sir Charles Batch. He has been here through thick and thin, and is a proven back up. That's just me though, I don't really wanna see a new QB, having to try to learn Todds Odyssey in a week. At least Charlie is around 24/7.
Only time will tell. ****ing horrible season so far. We won't quit, but the injuries are ruining the season. Hopefully everyone comes back.
