I believe the head-shake of disgust by Steelers quarterback Ben Roethlisberger—sans pads and helmet—late in Pittsburgh's 20-12 preseason victory over the Giants at MetLife Stadium said it all.
The head-shake came after a perfectly fine pass by fourth-string quarterback Bart Houston, who escaped some pressure before unleashing said pass, clanged off the hands of hopeful receiver Canaan Severin.
One has to presume Roethlisberger's disgust was the result of the dropped pass, and if he was disgusted, imagine how Houston felt.
But that's life as a backup quarterback in today's NFL—at least in the preseason.
