During the off-season it's up to the players to feed themselves (they will get nutritional guidelines, targe weights, and even some help meal planning).
Athletes get a 'Fuel Card' that provides one meal per day (M-F). Everything else comes out of their COA (monthly Cost of Attendance stipend). They can also get 'snacks' at the nutrition center (located by the weight room) that includes smoothies, bagels, oatmeal.. etc.
During spring practice, fall camp & the actual season the available food borders on gluttony (think Harry Potter dining hall).
Early winter, late spring & summer its all on the players.
