When will Chase Utley and Jimmy Rollins news stop being Phillies news? No one knows. When a player leaves Philadelphia, there is a small window of time in which any subsequent actions on their part - a big hit, a no-hitter, attempting to throttle their new team's best player by the neck for a perceived slight - can still be considered relevant in the Phillies universe.
Why, just yesterday, I stopped myself from putting up a "Ha ha, Papelbon filed a grievance against the Nationals" post, which is good, because hours later, Maikel Franco did the same against the Phillies.
