On the spectrum of high-risk sports deals, building a stadium for an expansion team in a one-year-old women’s soccer league that’s only signing a five-year lease has to be considered on the wrong end. On the bright side, Kennesaw State University’s stadium for the Atlanta Beat will cost only $16.5 million, and is being funded substantially by two anonymous private donations, along with student fees and venue revenues. And at least the Beat won’t have to struggle along anymore in their outmoded three-year-old stadium.
