AB, by most accounts here, was overpaid in his recent contract. I think it's important at this stage of the team's development that every player has the capacity to exceed the value of his contract.
At 8M a year, AB is a consistent shot, 1-2 ppg, and a healthy first few months, from being a very legit 8M (or more) SG. I'd say it's actually his health that's the biggest variable in whether the contract is viewed as over or undervalued by the trade deadline. Of the C's current roster, I think only GWallace has a salary that unquestionably exceeds his value. Bass and Green are looking about right to me.
