He will be wearing number 0. Have we had a player with that uniform number before?

I was just about to say the same thing. I don't remember seeing a #0. In the last decade I remember our numbers starting at #2 since #1 is retired. 

The QBs have been numbered anywhere in the single digits or teens a la NFL numbering. Factoring in the retirements of #7 and #16, and the unofficial retirement of #12, we still have #18 and #19 available.
