That is the perk of being a fan, I get to not like the entertainers if they don't do a good job. KD did that by his weak move, so I get to hate it all I want.
Also, there wasn't two options and money is a perfectly good reason to stay at OKC and to win and overcome his failings. But continue with your narrative.
Bottomline, KD is a insecure player who is seeking approval wherever he can and still doesn't have enough confidence in himself.
