As the title indicates, the Wall Street Journal ran an article titled "What the NFL Can Learn From Rugby". The article discusses the difference between tackling in football versus rugby, as well as American Football teams that have adopted the strategy.

The rest of the article details more points about tackling from the Buckeyes as well as the strategy adopted by the Seahawks, MSU Spartans, among others.
