"Max" means something less than it used to mean, under the new CBA.
Rondo's not worth a "Joe Johnson-Max"-type contract (6/$120M), but they don't exist any more. The "max" deals that are being shown to guys like Hibbert are 4/$58M, or $14.5M/year. That seems about right for Rondo - and would be a massive underpayment for the league's REAL superstars, the LeBrons and Durants.
