Why would he try to miss a FT down 5 with 3 seconds left? It's not like if they got the offensive rebound they could score 5 points. If they were down 3 it would make sense, but not down 5. Very weird.
Very little incentive to make it either. Could get a real quick tip in and then steal it and hit a 3. If he makes it they are gonna lose anyway. Announcers expected him to miss on purpose. Didn't seem fishy me, just unlucky that it still went in.
