claiming something and actually writing the checks are two very different things. am i saying he's full of shit? no - more along the lines of "who the hell knows."
regardless, this contract is unquestionably horribly overpaying and he wouldn't sniff anything close to this on the open market. the question is whether or not that ends up mattering - hopefully not, but again we're back to "who the hell knows." only time will tell.
finally, just because an owner is willing to spend doesn't mean he should just throw out huge amounts of money without a care (see: prok in brooklyn). it's still money, and billionaire or not $30M is still a fuckton of money. in the end, the cavs just overpaid for both bigs they re-signed.
