The Florida Gators ran this sideline out-of-bounds play during the 2008-09 season. This is a simple action that allows you to put your best player in a situation to score off a single screen.
If neither 2 or 5 are able to get free. 3 should pin-down for 1 and 1 will get a dribble hand-off from 4. OR 1 can sprint opposite and run a 4->3 side pick & roll.
