the obvious change to how Philly has fared in this series, other than Embiid's return, is the level of D that Philly plays. They've been all over the C's before they hit half court to slow them up and the C's aren't getting their usual open shots (and missing them when they do). The C's aren't pressuring Philly at all. They get the ball up the court as they please with more than enough time to get into their offense. C's apparently can't get through Philly screens whereas Philly can draw offensive fouls on C's screens.
this is on Joe. C's can't hit shots when they're open but Joe has no variations on offense other than bomb away so they're dying by the 3 under pressure.
