Drawing a charge from Williamson is equivalent to getting hit by a car

Duke freshman Zion Williamson has yet to be called for a charge during the regular season, and based on one physicist's assessment, it's easy to see why his opponents have avoided trying to draw a foul.

Ben Cohen and Andrew Beaton of The Wall Street Journal asked University of Lynchburg physicist Eric Goff to review clips of Williamson's charges to determine the maximum force of impact. Goff reported one Williamson charge to be 300 pounds - "the equivalent of the average force during a similar, head-on collision with a Jeep traveling 10 miles per hour," Cohen and Beaton wrote.

They also spoke to Chris Arp, a basketball coach and physics teacher at Spartanburg Christian Academy who faced Williamson's high school team 10 times in a four-year span. One of Arp's students, Jonathan Gaminde, asked him in class one day how much momentum a force like Williamson generates.

Gaminide once made the mistake of positioning himself between Williamson and the basket during a game, and compared it to a quarterback getting blindsided by a defensive end.

"I quickly realized what I had just done," Gaminide said.
