You don't understand the kind of player Lin is. No one is "feeding" him. He "feeds" them, with assists when players converge on him. I agree with you to a point when you say that great players make their own circumstances. That may be true for a post up type of player, but not al types. On a practical level, when you're a point guard and starting the offense, and the game you excel at is the pick and roll with a spaced court, the coach/team should provide that circumstance. To not do that, and even to put Lin into a #2 guard where he has to wait for someone else to create, and then often get him the ball in a disadvantageous circumstance, makes no sense at all. Take most great players, and put them into a situation they're not well suited to, and they will not do well. Put Larry Bird at point guard, or make a point guard a small forward, etc. You're looking for mediocrity if not out and out failure.
Yes I do. Not that good. That’s the simple fact. He’s not good enough to build a team around, but by your own admission needs the team to be built around him. He simply does not have the skills to warrant that. Which is why he spent almost all his career as also ran. He’s just not all that.
