Beal doesn't become a Sun without the KD trade happening first. I think we can all agree on that.
I don't know how much blame falls on Beal, he's not blameless, but we won't be able to get an accurate measure for a while. Financially he pushed the Suns over the edge but the KD deal emptied the cupboard.
I want to move on but I'd rather eat the $50+ million a year this year and next vs being saddled with $20 million a year over the next 5. If Beal will be a super sub, let him try, but tell him the minute he can't suit up for a game is when he's sent home for the duration of his contract.
