Wow, so many ignorant people refusing to accept that you don't have to be a perennial Pro Bowler to teach someone how to be a good QB. Like for example, if someone just doesn't have the natural physical abilities to be great, how does that keep them from being able to use their mental abilities to help someone who DOES have the physical abilities?
Do they think every coach was a legendary former player at every position on the field? By their logic only the best players can qualify to teach.
Barkley is the arguably more talented primary backup, Anderson is the mentor and Barkley's backup for when Allen gets hurt again. Do we want to have to hire someone off the street again? Why dump Anderson just to add another 3rd string player who won't make any impact?
