 What's Klay Thompson got left in the gas tank? Is he a key addition for the Mavs, for them to defend the West? Yeah, I thought Klay Thompson had a better year last year than a lot of people thought. If you look at his numbers, he averaged around 18 points, made a really high amount of three-point shots. I know he got demoted from starter to bench, and I know his defense has slipped a little bit.
