Here's the initial segment.. Eagle was being a bit of a douche when he says 'I have no idea what youre talking about'.. I'm sure there were plenty who tuned in who maybe didn't know what a slip screen was.. it's a pretty common thing for an announcer to explain a common sport play for those unaware. Fratello never seems to catch on to this, and Eagle goes with the 'that shot was inside the arc so it's 2 points.' Later on in the game, maybe he didn't want the fans to believe he really didn't know what a slip screen was, so he calls out Fratello as his joke failed.
