A few years ago USA Football, the national governing body for youth football, partnered with the NFL to create a new tackling technique teaching program that they claimed would dramatically reduce head injuries 

Heads Up Football.

The assertion was that if more kids learned this technique, the sport would become much safer. It followed a time where a lot of new information about head injuries was being discovered, like even seemingly moderate impacts to the head can have far more lasting effects.

The technique was geared to have players tackle with heads up, instead of using the helmet as a battering ram.

But now it appears the numbers that backed up the safety claims  was miscalculated. We’ll talk with Alan Schwarz, the New York Times reporter that uncovered the discrepancy.
