From his rookie year through the 2018-19 season, he earned just under $79 million in salary. But in July, he signed a five-year contract worth approximately $190 million.

But when you make that kind of money, wasteful spending comes into play.
"I made some mistakes. Like hoarding -- especially with the clothes," the three-time NBA champion recently told Maverick Carter of Uninterrupted.

"I had these hoarding tendencies that I had to rid. It took some time."

"If I got to buy in more than once ... when I have to tell my financial advisor what happened, it's not good. It's like getting brought into the principal's office."
This is example No. 958 as to why Klay is the best.
