Josh Richardson is a guy I would 100% buy low onThey wouldn't do Barnes... they wanted the world for him at the trade deadline. He'd help on the glass and is a bit more versatile... agree.
I think if you move Bogey you might look at a guy like Rudy Gay for the mini-MLE. Depends on what you got for him.
I could see Dallas being interested either for Kleber or Richardson (they'd pack his bags). Josh has gotten so bad though... he peaked when everyone thought he was rising. Kleber makes less and can do the stretch 5 and survive at the 4 alongside Rudy... IDK its kinda hard to move any of these guys.
