We have to wait to see where the caps are, where the contests are, and how the other archetypes affect this situation. The whole point of a sharpshooting C is that they are tall and accurate. If you play them straight up, they pull the defense away from the basket and open up the floor. The issue is what kind of defensive contest affects their shots significantly and how effective they are at creating off of the dribble.
Mike said this as been tweaked, so we'll have to wait until good players start attempting to use these archetypes, and then start defending them, to see what it really looks like. If you make the decision to have a tall, agile defender stay at home on a sharpshooting big, that should be enough to mostly neutralize that weapon.
Right now, people are completely writing off defensive archetypes, but this might be a case for having a tall, versatile, three to four position defender.
