U.S. ski legend Bode Miller has his son run up a mountain.

Video polarized his Instagram followers and attracted the attention of several American media outlets. Some are in favor of Miller's way of upbringing, some are fiercely critical. In the meantime, the comment function under the video has been deactivated. For Miller, it's "so much more than a football game," but rather "teaching our kids to never give up" The 45-year-old himself sits in the car and drives behind.
