The original trade is insane. I thought it was someone who might have bumped their heads but it's just trollboy16f.
PER 36 (this is one of those times per 36 works well):
IT: 24.8 ppg, 3.3 rebounds, 6.9 assists, .562 true shooting percentage, $7m/yr contract
Butler: 20.4 ppg, 5.2 rebounds, 4.7 assists, .563 true shooting percentage, $19m/yr contract
They're basically the same age. So offensively, Butler gains you absolutely nothing. Nada. If anything, IT is the superior offensive player. Defensively, there's little doubt Butler >>>> IT. So if everything is equal, I'd rather have Butler.
But everything isn't equal. So is Butler's superiority on the defensive end worth $12m a year? Maybe, but probably not. Is it worth $12m a year AND a top 5 pick? Not just no, but 7734 (calculator humor) no.
