Howe's Research About the Commercialization and Professionalization of Welsh Rugby

Howe's research about the commercialization and professionalization of Welsh rugby union football showed that:

A) the players liked being considered "mortal engines."
B) the pressures on the players to take risks with their bodies increased as the sport was transformed from amateur to professional.
C) none of the injuries in the sport resulted from legitimate or "legal" tackles.
D) the professional form of rugby union was safer than the amateur form because the sport rejected the influence of contact sports in the U.S. such as U.S.-style football.
