No.
He was bad offensively this season WITH RR!
Now, if you say that not having a PG at all makes AB worse, I'd agree. AB having to be the PG and forcing it is his main problem. Then there is his confidence, even last season, b4 AB gained confidence in his offense he was TERRIBLE! He is the true definition of a person who looks outside for confidence offensively (unlike someone like Kobe or PP, they think if they miss 20 shots in a row, they truly believe 21 is going in, AB hopes/wishes 21 is going in)... if he misses a couple shots he continues to miss. Just like when he makes a couple in a row it almost becomes automatic. If AB can put 2-3 good offensive games together I think it will help him tremendously. Also, doc needs to stop making him a PG b/c he isn't one!
Edit: we always knew AB's flaws, he was never suppose to be a PG (even though Doc tried to force it on him a few times b4 Ray went down)! Even last season everyone would cry when Doc tried to let AB handle backup PG duties.
Get a PG and AB goes to his natural 2!
RR makes everyone better of course... but with or w/o RR, AB isn't a PG and that's the problem. He is like Ray, stand and shoot, not a facilitator or creator.
