He hasn’t done some masterful coaching job; he’s gotten favorable matchups each round. This was the Warriors title to lose since February. Steph has carried this team and this sham coach the entire year, despite Kerr’s insistence on trying to ruin it.
He was close to blowing the finals until he benched Draymond. That’s an adjustment I’ve been saying for two years. If you want to know who Kerr is, look at his record in games with no Steph Curry, including the years with Kevin Durant.
