I think it's time. Banks is bringing nothing to the table on returns or offense. I would cut him this week and let others handle returns. In terms of the option back, we could use someone like Robinson...he might have more ball security anyway.
Our offense is progressing to the point where we don't have to pray that we return punts or kick offs for TDs. The most important thing about our return game with RG3 under center is to get the best field position you can and not fumble.
