The point though is that Marco was more of a known quan y. You know what he does well and what he doesn't do well.
Anderson is limited too right now, but he's still developing, which is both good and bad. Good because he can get better, bad because it's hard to play him in high stakes games when you don't know if he's able to raise to the occasion.
Which is why I think he will still have a minimal role this season. I think Pop is still watching him and Simms to grasp what he has there and how to use them. It doesn't mean Kyle is not good enough, just that he's not a known quan y just yet. His time will eventually come.
