PROVO, Utah — LDS missionaries — or at least BYU students dressed up like them — were expected to invade the Marriott Center for Wednesday night's game against San Diego State.But, as it turned out, only a few students donned white shirts and ties in response to what Aztec fans did last month when the Cougars defeated SDSU in San Diego.During BYU's 71-69 basketball victory there, a throng of San Diego State students dressed up in missionary attire to mock the Cougars and The Church of Jesus Christ of Latter-day Saints. They also displayed derogatory signs and, at the end of the game, they chanted, "You're still Mormon!"One of the homemade signs in the stands at Viejas Arena was directed at BYU star Jimmer Fredette. "Which wife gave you mono?" it read, referring to Fredette's bout with mononucleosis earlier in the season.Leading up to Wednesday's rematch with SDSU, some BYU students, through social media sites, called on fellow students to dress like missionaries — including name tags — to show they are not ashamed of their faith.While BYU's student section was packed during the Cougars' 82-68 win Wednesday night, only a handful of students actually followed through. For the most part, BYU fans kept religion out of the game.There was at least one religious-theme sign that a fan wearing a BYU jersey proudly held aloft during timeouts: "Aztec ancestors wrote the Book of Mormon."
