Stephen A. Smith says it more eloquently and succinctly than I will here: http://espn.go.com/video/clip?id=16762272&ex_cid=sportscenterFB&sf30235644=1. His opinion is similar to mine, now that I've had time to consider it.
It's like playing soccer when you're a kid. You're doing well, but then, the other side takes the momentum from you. Scores a couple. You're the best player on the field, and you decide to jump sides. That's juvenile, and we know it.
OKC has the talent. OKC has the skill. OKC has the players. They were very close to knocking off the Warriors, and probably should have. From outside, it looks like KD just doesn't have the guts to tough it out and try again.
Imagine if LeBron had cut his contract and bolted to the GSW after his 2015 loss in the Finals. What would we think of him then?
Right. Now, you can think that of KD. And I do.
