There's a difference between saying they give us problems and saying we can't beat them. All Doobs said is that mobile QBs give us trouble he not once said we will lose just that it's not a given that we will win.
You can be critical of a team and not be bashing you can talk about areas that need work and not say we are going to lose or that the sky is falling. Chill out a little. Doobs was just stating an opinion on an area that he thinks needs work no need to make a big deal about it
