Who is the best Chiefs backup QB since Rich Gannon?

[RealSNR]

Poll forthcoming.

The criteria:

1. We are talking about players who have served as the primary backup during a given game. They are first off the bench. Third stringers who never move beyond 3rd string do not count (i.e. Joe Germaine or Ted White)

2. A 3rd stringer who is pushed into the backup role when the 2nd string QB enters the game is considered the primary backup QB. Thus, Tyler Bray and Aaron Murray, who both became backup QBs on days that Alex Smith was inactivated, have been backup QBs for this team.

3. Non-QB passers such as Mark Bradley are not eligible, despite the fact that they were active players who would have been taking all the snaps should anything have happened to the two QBs above them on the depth chart.

4. We are evaluating QBs according to their playing ability when they were Chiefs. Warren Moon's career prior to being a Chief should not be considered in your evaluation, nor should you consider Todd Collins' starts with the Redskins and Bears.
