Do the Ravens Need to Get Another Backup Quarterback?

I heard several local sports talk hosts say that the Baltimore Ravens need to go out and get a veteran backup quarterback to replace Marc Bulger.  The idea being that if Joe Flacco goes down, a veteran would be able to step in and still lead the team to the Superbowl.  I personally don't think that the Ravens don't need to do this for three main reasons:

Reason #1 - Joe Flacco rarely gets hurt.  Marc Bulger made a whole lot of money last year just to carry a clipboard.

Reason #2 - I would rather use that money to build more depth on the offensive line or to improve the pass rush.

Reason #3 - The impressive play of rookie Tyrod Taylor. Tyrod Taylor has played so well in the preseason so far that I have no problem with him backing up Joe Flacco.  Remember 2008?  Joe Flacco didn't have much experience either when he came in as a rookie and the team went all the way to the AFC Championship game.
