It's obvious Ainge still believes this team can contend, otherwise he'd have done what the Blazers did - ship out veterans for picks without taking back any contracts.
Plus, that they can contend as it is - otherwise he'd have done some small trade, like Wilcox and second for some big that can eat some minutes.
We'll see if he's right or not.
IMO, it's not as idiotic as what he did 1 year ago or when he decided to sign Jermaine O'Neal (even though those who are Ainge fans first and Celtics fans second will still rationalize those as great decisions), but it's close.
