 Being a head coach, as long as you get people to do the part that you don't know how to do, and you just lean into the parts that you do know, and then you've got to have great work ethic because it's going to be a lot. Of course you can do it. It's been done in the NBA. Steve Kerr never coached before. You've got to lean into the parts that you know and hire people for the parts you don't know. I think the question for them is, what do they add personnel-wise? Because now LeBron, instead of being a strength, is a weakness for them defensively.
