I think you are forgetting about Paul Pierce in terms of something right in front of us. We can play Green at SF and slide Pierce to the SG spot. I don't see any reason why he couldn't play there for up to 20 minutes until Bradley gets back.
Great point! I can't believe I haven't considered that possibility. Here are my initial reactions:
Pros-
We won't need to waste the BAE/ overpay somebody/ give away assets in a S/T.
That allows us to use the BAE on steamer or some other front-court help if we need to.
It gives JG more minutes which should allow him to develop chemistry with RR et al more quickly.
Cons-
Paul is a little slow for the 2 spot so if teams go small/quick it would hurt us.
PP is old- the last thing we need is him to get more minutes.
If AB is out longer than expected we'd be pretty much screwed.
Those are just my initial thoughts.
