I'm all for giving Jones and Boston both a shot. It's very difficult to imagine that pair being worse than the DeCoud/Harper pair. At least the young guys can actually run. What's the worst that could happen? The D gives up 30+ points on our way to getting blown out? Oh wait, that's happened 3 times already this year.
Jones and Boston are also young and can improve vastly with game experience. With DeCoud and Harper you know what you are going to get, and it's not good.
