I still don't believe that, particularly in goal-line situations, when the
entire defense is lined up on the offensive line, that it would be impossible or impractical for a running back to run wide, where there is no one out there to defend him. That's the whole rationale behind rolling your quarterback out. Are you telling me our quarterback is faster than all our running backs? I don't buy it.
An analogous situation that also baffles me is the practice of kick or punt returners to run right into traffic and get swarmed under. So often I'll see the vast majority of the defenders (and blockers) clumped toward the middle of the field, and for some reason, the returner will head for that exact spot and get completely buried, despite the fact that there were huge running lanes on either side. Is the concept of running behind blockers so ingrained that they do it even when it impedes their forward progress?
