you act is if each team in the NBA runs one play and that's it. Leron, D-Wade, and others iso a ton, I did not say otherwise (though you act like I did), the point is when they're not iso'd they're looking to cut and get easy buckets most of the time and it helps their teammates on the occasions they get the ball. The other players aren't all just catch and shoot guys other them, and that's what Branon/Nate do, everyone else on the floor is catch and shoot when he's out there. I know he's capable because he did it well at Washington playing off NateRob.
I'm not saying Brandon shouldn't be our main weapon, but on the plays that he isn't (do you think he should iso 80% of the time) he needs to put more effort into moving w/o the ball.
As an aside, Brandon will/(maybe does) have a better supporting cast than Lebron ever has and Wade has the last couple of years.
Don't take me out of context again and stop thinking so simplistically, a third grader could see the holes in your limited logic.
