Texas-San Antonio is the 23rd-highest scoring team in the nation. The Roadrunners average eight more points per game than Florida Atlantic. They have a big backcourt edge with Jhivvan Jackson and Keaton Wallace, who average a combined 47 points per game. 
The Roadrunners have scored 77 or more points in 10 of their last 13 games. 
I don't see Florida Atlantic producing enough points to cover let alone win the game. The Owls have not been playing well losing and failing to cover in four of their last five games.
