Uh, yes. The Nets just moved to a major metro area where they hope to grab a slice of the juicy NY revenue. Plus they're owned by a Russian oligarch. Neither applies to the Thunder. The Thunder, like the Pacers, need to watch their budget.
And you're right. It doesn't make sense from a basketball or asset perspective. We're talking financial perspective here, in that OKC will have to pay a lot of $$$ in luxury tax. Especially if they keep this core for the long term (Hello new "repeat offender" tax in the CBA!)
