Input: Question: How many teams are members of the athletic conference that added BYU and Pacific in recent years? Passage:Spokane Arena, in addition to its duties as being the host of Chiefs and Shock games, also has served as a secondary home for the men's basketball programs of Gonzaga University and Washington State University for nearly every year since opened. Washington State has played 33 matchups in the Spokane Arena in 19 of the 22 years with a record of 18–15 (1–7 vs. ranked opponents), while Gonzaga has hosted 18 games in 15 of the 22 years with a record of 12–6 (1–2 vs. ranked opposition). In-state rivals Washington State and Gonzaga have faced off against each other in the arena on five occasions (1995, 1996, 1998, 1999, and 2014) with the Zags owning a 3–2 record against the Cougars in those games. The Bulldogs' faced off against local rival Eastern Washington University at the arena in four consecutive years (2002, 2003, 2004, and 2005), each won by the Zags, but just like with the Cougars, the rivalry has gone dormant due to the rise of the Zags' program to major status since the late 1990s, while the Cougars and Eagles have not seen much national spotlight. Washington State has often hosted home games at the Spokane Arena as a part of its Pac-12 Conference men's basketball schedule, holding a 7–9 against conference foes in the arena, facing UCLA (1996 and 2004), Oregon (1997 and 2011), Oregon State (1997, 2011, and 2017), Arizona (1998, 2001, and 2006), Washington (1999), USC (2000 and 2004), Stanford (2004), California (2005), and Colorado (2014). With Gonzaga's rise to prominence, the Zags were able to bring high major schools like Washington (1998), Georgia (2003), Memphis (2007, 2009, and 2011) and Oklahoma (2009) to the Spokane Arena, with the Gonzaga holding a 2–3 record in those matchups, but with conference realignment and the West Coast Conference's additions of BYU (2011) and Pacific (2013), the Zags have been more selective and limited in their scheduling with four less matchups in their non-conference schedule, so they have only played in the Spokane Arena once since 2012.
