CBS ROLLS EYES AS PVI CAN'T PRODUCE YELLOW SNOW

Unlike Fox Sports who has all their technology on site for each of their weekly NFL games, CBS Sports deploys PVI's "Virtual First Down Line" from NEW YORK for all but their "A" game each week. This saves money but takes risks, especially when Mother Nature gets involved.

And when it snows as it did on Sunday in Pittsburgh and Cleveland, visually detailing the line of scrimmage and yards-to-go proved impossible, leaving CBS' viewers out in the cold.
