The Aztecs are excited that they've made this far.
"Reaching the semifinals is something that we penciled in as a goal when we first started this whole thing three years ago with the program," said SDSU head coach Dan Payne in a news release. "It's great because it's for the kids. They busted their butts and they've worked really hard and they made this a reality."
"They're a very good team, very quick and really good execute at great speed," said Air Force Falcons head coach Tony Mazzarella of the Aztecs in a Cal news release. "They're going to be a handful for anyone that plays them."
