You think both are overpaid?? It wasn't too long ago when Todd McCullough, Matt Geiger, Adonal Foyle, and Jim McIllvane were taking teams to the bank. $5 mil a year for Darko isn't bad considering he was playing pretty well in his role in Minny. 5/$32 mil for Gooden isn't bad either considering he averaged close to 15/10 for the Clips last season.
I think these teams should be more worried about the contract length than the amount. Big men get paid extra for being big. But, signing a 5 year contract is a big risk if/when their production goes down from their currently mediocre level.
