The Cougars advanced that far in last year's tournament, losing to Penn State, the eventual champion. This year, they are ranked sixth in Division I by RugbyMag.com.
"We have a good shot," said Kirsten Siebach, the team captain. "We're certainly one of the top rugby teams in the country."
No matter their performance, however, BYU will not advance past the Sweet 16 this weekend.
Siebach said all 35 team members are practicing Mormons, and because USA Rugby scheduled that round on Sunday, the team has decided to forfeit if it wins its game Saturday against Wisconsin-Milwaukee.
"We're obviously just very frustrated," said Siebach, a senior. "We don't want to put USA Rugby in a bad light, but at the same time we feel like we've been treated wrongly."
