...who could be worse on the field than Clausen. Remember teams like having continuity in the QB room, probably a big reason Anderson came back.
IT DOESN'T MATTER.
If you're down to playing QB #3, you're screwed anyway.
If you sign Derek Anderson as your backup, your #3 guy isn't important.
The only time we really need to worry about drafting another QB is when we're ready to move on from DA or he's ready to move on from us. Then use a 2nd or 3rd or 4th rounder to draft a guy to develop as your backup.
