Exactly. To both of those comments.
Klay recently said, "I don't feel like I sacrificed at all, I'd rather be a part of something that could leave a legacy. There is more to basketball than getting yours, or being the guy. I hope I do this for a long time for the Warriors."
Now I'm generally of the opinion that actions speak louder than words but that seems pretty clear from Klay. Plus his actions since he was a high school senior seem to back that up.
Coming out of high school he had offers from a number of big programs including Michigan and Notre Dame but opted to go up to Pullman to play for Washington State because he could play ball and smoke weed without being noticed. He knew he'd get to the NBA either way.
Regardless of where he's playing, he's going to end up as the 2nd greatest 3 point shooter of all time behind only his teammate. If he's stays with the Warriors he has the opportunity to go down as one of the most successful SGs of all time. If what he says about building a legacy is true, I don't think he'll have any interest in leaving.
Lastly, as his dad put it: "Klay's life is the best. All he does is shoot 3's, hit on girls on instagram and walk his dog, Rocco". Sounds to me like even his dad knows this is exactly the kind of life Klay wants to be living.
