While i agree with you that losing Brewer isn't the end of the world and James Anderson is an ok backup, i haven't seen any indication that James Anderson is a good defender from what I've seen so far. He showed he can shoot (we all knew that and i'm glad he can do that in the big stage), but defensively I haven't seen anything. He doesn't have size or enough athleticism to defend the 3 and the only reason he is going to backup RJ this season is the lack of options. He is a SG and that's how i see him in the future.
