Scott Smith’s Top Plays for UFC Vegas 117: Allen vs Costa

UFC Vegas 117 will be a 13-fight slate from the Meta APEX on Saturday night, headlined by featherweight technician Arnold Allen looking to halt a 1-3 skid against streaking Brazilian Melquizael Costa, riding a six-fight win streak and the second-highest adjusted ELO on the card. The co-main puts Doo Ho Choi’s long-awaited return under the microscope opposite pressure-volume specialist Daniel Santos, and the prelims run deep with live underdog opportunities at bantamweight, welterweight, and a stacked women’s section featuring Ketlen Vieira’s first walk to the cage since 2024. Below, we break down our top plays and optimal salary allocation for cash games, and the DFS plays that meet our model’s threshold.
