Don't rule out the idea of San Francisco attempting to acquire a veteran quarterback, even if Smith is re-signed. Making a move for Palmer or McNabb would probably instill immediate confidence in the current players. Having a legitimate competition for the starting job could also bring out the best in everyone -- especially Smith.
This would be the best thing for the team to do if we ever have cba in place. Bring in as much competition and let the best man win and if Alex wins the competition then more power to him.
Also its good to have a back up that can come and perform should Alex fail (and he probably will fail).
