The thing I like about Joerger is that he shows confidence in the team he has out on the floor, letting them play through adversity and giving them a solid chance or two to figure it out and adjust. Experience and reflection...that's how teams and players develop.
As for the odd pairings (i.e., Cousins and KK), there are times that he sees potential for good chemistry, based on his experience with many different types of players. The key word here is potential....meaning that little if any chemistry exists at the current time. This nothingness is what we see as fans, and it frustrates us, but Joerger will give it a chance to grow. He'll exercise patience and show trust in them because...well...he's Joerger, and he knows a thing or two about player development.
I trust Coach's experienced-based ability to (a) spot potential and (b) walk the line between nurturing it not having it cost us the game. It doesn't always take off, of course.....that's just life. And basketball.
