Jrue was bricking the whole series, and almost the entirety of Game 7 (every other post in the game thread was about Jrue shytting the bed), until he came alive in the dying moments and scored the Bucks' final six points in the 4th quarter. That could've easily been Harris. You can't blame the coach for putting the best players out there for their specific use, and then blame the coach for those players not performing. Shooters go through droughts, it just so happened to be at the worst possible time for Harris.
Not to mention, Harris shot 50% from behind the arc in the series prior, so you can't just bench someone of that ability when there's no better alternative.
fukk Joe Harris
