If your basing your opinion that KD took the easiest path to a championship, that happens all the time in professional sports. So do you think KD should have stayed in OKC in whole career out of loyalty and potentially never won one? Isn't the goal of sports to win a championship and put yourself in the best position to accomplish that?
Golden State wasn't necessarily a "super team" before KD joined them. He made it a superteam just like LeBron made Miami a superteam by joining with Bosh and Wade. Whether you "joined" or "created" a superteam really doesn't matter. You put yourself in the best position to win a championship. KD made a great business decision to join Golden State. Ask yourself what would you have done if you were him??? Stay in OKC and continue to be good and most likely never win a Championship let alone 2 finals MVP awards to put yourself in a position to accomplish things you dream about as a kid.
