Rasheed Wallace is known for his trash talk and way with words. From "both teams played hard" to "ball don't lie," Wallace has coined phrases that just kind of became part of the NBA culture.
After Afflalo missed the first of two free throws, you can very clearly hear Sheed yell out, "Yeah Aflac!" I'm assuming he's calling Afflalo "Aflac," but who knows. Maybe Sheed just says that when he's happy. Maybe he got a great rate on some health insurance and wants to tell people.
Good to have you back, Sheed.
