A mid level-ish deal for a 6MOY and second scorer of this team is a steal in any language. The guy even played for pretty much the vets minimum this year.
I am disgusted about his playoff performance just like any of you, but this is going to be a trade asset at worst. From a basketball point of view, rest assured that we need this guy (at a good level) to get to the finals.
And most importantly, not signing him wouldn't mean getting anything back. Nothing. We're over the lux-tax and will be until Melo, Stat and TC finish their contracts. With that in mind, any argument about so called better players for less money is not real.
