We are redesigning our app and the current one you need to hit the back button to view all Divisions to get to a new Division Details page. We are looking for the best UI option to just change the division on this view attached. We are leaning towards a down arrow near the "5th Grade Boys" to open a select list to choose from. Is there another good design up that could be done for iOS and Android?
