As much as I would love to see it, from the little I have seen from Bradley, he is nowhere close to ready. He has looked completely lost out there on offense, and completely overmatched.
Now, perhaps a big part of that was throwing him out there at PG (which I am not sure he will ever be). He may be more comfortable if they ease him in as a SG...but that is a big if.
With a young guy like this, I think you risk doing more damage than good by throwing them out there before they are ready. You don't want to destroy his confidence, and if he is not comfortable with the system yet, or the speed of the game, he is going to really struggle.
Now, perhaps I am wrong, and he has shown more in practice suggesting he is ready, and that was just nerves the other night. But based on what I have seen, I think they should be looking to send him down to Portland for a while to build up his confidence, and have him work with the coaches a little longer down there to learn the system and the NBA game. Then, give him another look in January or February (since West will probably still be out), to see if he is ready.
