Did people really believe Brown was a #1? I thought it was fairly obvious he is a #2. He isn't a good enough ball handler, creator, or passer to be a #1. And because he is serving that role, everyone else has to move up roles for which they aren't suited i.e. White is trying be a #2 when he is really more like a #4, PP is a 3 when he should be a 6th man, etc.
I think they may need to start Simons and let him serve as the #1 scorer. He can at least create good looks for himself. That moves everyone else down to roles they are better suited for.
