I don't think either need to go to the D league. Eventually I see them playing together as well. Bradley D's the other teams' point, they can switch running the point depending on the sets.
Bradley - great D on opposing points that has value in "any" game at certain moments. He also cuts lanes decently off the ball. I'd like to see him getting the ball more off cuts on the way to the rim. Break points and mid range shots
Moore - a really good and diverse talent off the bench. May never be a starter but a long term 2nd or 3rd string guy.
I'd like to see Moore get some minutes at point if you don't need ball pressure. But with his stroke, I'd also like to see him playing the Ray Allen role off the bench and with Rondo at the point. Let him get some spot up three in the half court set and some drift threes on the break.
This kid has a poor shooting percentage so far, but he is a very good shooter with an excellent stroke. That is not because of last night's game it's because you can tell by looking at his stroke and by what he has historically done throughout his college career. The more he settles down and as his confidence and comfort level grows, we'll better and better %'s from him.
He's not a jaw dropping athlete but he has one athletic attribute that will allow him to play solid D at this level. Very, very long arms. This means he can take a 1/2 or full step off his man and still bother him. And when his man blows by him he can still trail him and stay with him due to his length. That combined with his intelligence will make him a solid NBA defender. It's similar to how Mchale used to guard the faster SF's sometime - by using his length - this is just at the guard spot.
I'd say by mid way through next season, once these two have more experience, you will be able to play them together off the bench.
As someone else said, continue playing them when their strengths dictate good match ups - continue developing their weaknesses.
Moore: get stronger, continue working on his D and learning rotations is about it. He does everything else fairly well
Bradley: Ball handling, ball handling, ball handling and his shot. He gets these down he can get anywhere on the court and he'll be at the foul line all night.
