I tend to agree with Roy, that Green would be an upgrade for us. (Unless, like Who, someone buys in big to Giddens' potential. And, hey, I'm all for optimism and faith in Ainge's nose for finding back-of-the-draft talent.)
Compared to T.A., Green is equally aggressive on defense, but less mistake prone. Same story on the offensive end.
Willie doesn't score quite as efficiently, fewer trips to the line?, but he's far, far better on the catch and shoot. T.A. posted a 28% eFG last season on jumpers...
The biggest knock on him is that he doesn't reliably rebound or make plays for others. He's offense off the bench. And I like him, though more alongside Rajon (or Rubio? Ha.) than Eddie House.
