The Big East is divided over whether to pursue Air Force or BYU as its 14th football member, while another option the conference is considering is creating a 16-team football league by adding Army, Air Force and BYU, industry and league sources told ESPN. On Thursday, recently hired Big East commissioner Mike Aresco reiterated in Tampa, Fla., that the conference will add a 14th football member, echoing comments that former commissioner John Marinatto made months ago that it would add another member from out West to get to 14 teams.
