The perplexing one not listed is Billy Volek. A little long in the tooth now, but out of football for only this year, and is a free agent. Had a strong Schaub/Flynn type resume as a backup and was seen by everyone as a potential starter. Amazingly, decided to go to SD as a backup rather than compete for a starting job. Has a career 85 rating and won a playoff game against top seeded Indy on the road in 07. Given that he never wanted the pressure of being a starter, would it be possible to coax him out of retirement to try and save the franchise?
