LooseCannon:
I don't anticipate Brooks turning into an all star, but I wouldn't be surprised if he turned him into a serviceable 3rd string off guard.
That being said, per my main point, I think if we could find the right 4th guard to go with Rondo, Bradley and Crawford, we'd be in very good shape in the back court for some time to come. As you mentioned a 3 & D wing would be very nice.
Rondo is an all star and Bradley has become very solid on both sides of the ball.
I like Crawford behind Rondo. He may be a loose cannon but he's one of the best junkyard dogs I've seen in a while too. He's a gamer, as Stevens said, and I think he and Rondo like each other pretty well so that bodes well for chemistry.
get me the 3 & D wing behind Bradley and I could really care less if it's Brooks and Pressey or a couple cheap vets in the 3rd string guard spots...
